nether_01 Playable map WIP Very early style brushwork in a stalker infested factory. Stalkers in a factory enviroment. A bit similiar to the child factory. Kinda reminds of a early citadel design as well. Has a few areas to explore, worth a look! There is a Citizen named Joe (Joe Who?) and there are apparently three killer Stalkers dedicated for it. Poor Joe.
nov_bor_001 Playable map WIP Very early borealis. Lots of brush use. A very early version of borealis as a whole! No stalkers but there are scripts, explosions and fire. Some NPC_MAKERs exist. Could be one of the earliest maps completed !

prefab_canals Canals prefabs. Some neat ideas here such as c17 buildings on both sides + streets and bridges crossing. Kind of like a european style village.
prefab_government Similiar to buildings2 but has less focus on residental buildings. Possibly some really early concepts for the palace building seem to exist in here.
prefab_handrails01 Antlion king with some handrails in a box.
prefab_industrial Industrial style setting, some huge power transformers seem to exist (model does not load)
prefab_industrial01 Same stuff
prefab_lockers Bathroom / prison lockers and facuets ?

proto_citadel_skybox C17 overview and the circular citadel model. There are some additional combine structures that aren't recognizable.
..._citadel_skybox3 Same overview but Citadel is bigger with no substructures seen on the above revision. Citadel design has been changed a bit.
proto_combinebridge Has parts from c17combine. Added bonus is a very cool bridge that looks a bit wierd, kind of like a rotating combine wall combined with walkable area! Height adjustable by rotation ?
..._combinebrdige01 Same thing but with more detail added and c17combine section removed.
proto_docks Docks in a coast'ish setting. one boat vaguely reminds of the first hl2 screenshot with the people waving from the ship.
proto_innerwall Very close to combinebridge, if any different at all.

proto_prison1 Very early drafts done with the prison, mostly trying out gameplay stuff here with a few enemies and turrets.
proto_riverbed Canals/Coast influenced river section with some houses.
proto_tree Wastelands with a few dried trees.

quarry_town01 Sketch WIP Very early ravenholm concept & draft A VERY early version of the town map. Has the entry and goes on a bit until where you first meet Grigori in retail. Whole theme is heavily leaned on mining and art direction looks very different.
quarry_town02 Starts to resemble ravenholm a bit more! Lots and lots of smaller details and buildings added to support the main theme. Textures altered to look more varied and closer to the retail ones.
quarry_town03 Sketch WIP Much stuff added, a lot got changed later on. Typical changes. Much of the layout will be used in the final iteration of this map. A pickup truck exists which was removed later on in the development.

quarry03a Exploreable area concept Digging site with combine, idea got scrapped. No comment
randalpond Small playable puzzle Prototype A water? puzzle with wooden structures. Town/dock themed Interesting puzzle section. Seems that you have to fill a tank with water. Not exactly sure how the whole thing is supposed to work but would be interesting to see it functional ingame.
ravine04 Exploreable area Concept Wastelands themed cliffy opening. Very large opening, wasteland themed and brush based cliffs. Not much to do. There is a huge hole in the middle where you can accidentally drop in to die.

rooftop_victory Small playable area Prototype Rooftops with a script and a stalker. Above area with one shack removed, citizens replaced with one in the opposite building named "lobber". Stalker is near the player in the start. Script test for citizen ?
rooftops02 Sketch WIP Rooftops map. Early stages of development. Above area, but earlier on in development. Covers a few blocks and has the older c17 style. No enemies seem to exist yet.
rooftops03 Isolated area, selection is same as roofshack_01. Has stalkers and some pickable items.
rooftops04 Full map again, the later part has been worked on. Some detail additions and other small changes.
rooftops05 Scanner paths and scanners added, some minor details here and there.
rooftops06 Some holders added for the paths in the air/against a wall.

rooftops08 Lobber spawner and his scriptings. Minor details here and there (wow)
rooftops09 Possibly details, can't really spot anything.
rooftops09a Same but stripped to only have the start location.
rooftops10 Playable area WIP Likely the last rooftops iteration before scrapping it. No comment.
ruins12 Sketch WIP, concept Streetwar'ish old style c17 section. Oldschool style C17 ruins, Odell NPC exists but no real logic (This could indicate stage of development and some story elements) Must be an early streetwar concept.
ruins13 Sketch WIP, concept Very little has changed. Some small additions.
scraper_base04 Sketch WIP Vertigo and a part of c17 around it. 'rooftop'-like design. Vertigo and it's surroundings. Shows some of the stuff cloe to vertigo. Player starts in vert. and makes his way out to a large building. Has some stuff seen in 'bullseye' (apartments hallway)

sky_walk11 Sketch WIP Much better at this point. Still much to do.. No comment.
skybox02 Exploreable area Concept Wasteland'ish 3D skybox with two buildings. generic 3D skybox. Two buildings in a wasteland-like enviroment. Must be a quick test/start for c17 outer walls ?
sniper2 Prototype Sniper and tar Second building added! Same as seen in sniper_street01 & 02. Could this be an very early draft of it?
sniper_street01 Test Prototype Snipers and different targets tested. A Sniper test. 'camostreet' design. Targets are 'joe' and 'pete' (proto_sniper)
sniper_street02 Test Prototype Snipers and different targets tested. Seems to be the same but with decals added in.

strider_street05 WIP Early? E3 strider maps. An early? version of e3_strider. Start and other areas seem a lot more basic, less polished. Has the smaller style sewer section WITHOUT hydras !
strider_street12 WIP Early? E3 strider maps. Much closer to e3_strider design. Start changed but the hydra area seems to be still the smaller one. Maybe it was changed only for the e3 show-off and then pasted on to 'under' maps ?
testroom_fire01 Test Prototype, concept Brush fire in a box Same kind of fire as seen in streetfire01. Brush based and in a box.
toxic_pit03 Explroeable area Prototype, concept Toxic, rocky area with cremators. Sealed 'rocky' area with supposedly hazardous toxic pits and cremators. The toxic idea made in to the final as the canal levels where you need the waterboat.
train_depot06 Sketch WIP Terminal area with some addition to the trainstation. A split from rather early terminal levels. Earlier than 'plaza' due to the mid-sized plaza section. Lot's of terminal/industrial removed to focus more on the actual station. Gates addedand a lookout
train_depot06a Same with more stuff removed.
train_depot07 Plaza changed slightly.
train_depot08 Circulal citadel in the 3D skybox. Some details here and there.
train_depot09 Small work done inside the station, plaza enlarged a bit, detailings here and there. The usual stuff.
train_depot10 Sketch WIP More work on the terminal. Plaza takes it on from here. Close to what plaza started on. Must be an actual gap between the first terminal levels and plaza > e3_terminal iterations.
VanceHQ Exploreable area WIP Early Vance Headquarters. A lot got changed later on. a _very_ early version of vance HQ. seen in c17_05_xx in a more complete form. Contains parking/indoors and there is a Vortigaunt. Must be a very early map. Brushwork is very basic.
wasteland_bridge05 Exploreable area. WIP, concept. Familiar bridge in a wasteland setting for the train. Same bridge used in canals_03 but a bit extended and has train tracks. Wasteland setting and a linear path to go on.
wasteland_testmap02 Exloreable area Concept Wasteland displacemenet horror. Very crude wasteland rocky displacements in a barrier-filled box with some tunnels and stuff.

MAP NAME .VMF What is it State or purpose What does it have Comments
canal_jetski Sketch WIP, concept Jetski in an canals-like setting. A rather unique canals map where you use a jetski. Design is not typical canals-like. Has houses constantly on both sides and most of them are in ruins/ blowed up. Everything is still devtextured.
canal_watertest Sketch WIP, concept Canals-like setting on foot. Very much the same but with metrocops and without the jetski.
canals_01_15 Playable map (use _14) WIP See /aaron/canals_01_xx See /aaron/canals_01_xx
canals_industrial01 Playable map WIP A reorganized bastille. A lot more work done. bastille reworked! A lot more detail and touches. Some surroundings seem identical to canals_01_xx so this was most likely the replacement map for it. bastille midway> end changed to start > midway.
d1_canals_01 Playable map WIP, concept An very early draft of the canals section. A very early draft of the retail canals map! This is the one after you get your recharge jolt from the vortigaunt. Mostly devtextured and very crudely/quickly laid out. Has some NPC citizens named boxcar_philly and drainage_doug :) Doug got swapped for that female rebel and Philly is in the car where you meet the vortigaunt. Visgroups reveal more canal maps, a lot was laid out in hammer at this point. Very much of this stayed, Mostly additions were done later on. Worth a check! Also has the old helicopter with paths. Links to trainstation_01_to_04 and tempcanals (read more on there)
d1_canals_02 Playable map WIP, concept, sketch A quick mix&match of existing canal maps to plan a route. entry shack (One you come in with the long ladders). Level changes to: d1_town_01. A lot of maps put together in a similiar manner as seen above. Starts from canals_03 (very early) Player starts with the buggy. Could be a placeholder for the airboat. _03 ends pretty abruptly and Goes on to canals_industrial01 (Reworked a bit). Paths split to three and the other two lead to nowhere. Middle path gets you to the familiar pass-thru tall hangar structure with combine. After that the structures start to change in to houses that resemble the town maps. Player gets off the boat and encounters a shack after a few alleys that is VERY similiar to the retail ravenholm
d1_tempcanals_01 Sketch WIP Maybe a isolation to work on this section? Earlier version of 'canals_industrial01' Less detail and stuff are a bit differently. Alternate spawns most likely link this level to d1_under0102, used as a teaser of things to follow.
d1_under0102 Playable map WIP, concept An very early draft of the canals sction. 'd1_canals_01' with more stuff. Things like the tar? puzzle from retail are missing and have a simpler "jump over" puzzle. Mostly the extra stuff is just non-missing pieces.

e3_seacliff Sketch WIP, Prototype, sketch A section of cliffs and dried seafloor, buggy as well. Many early elements can be seen in here. Not sure on where all originate from. Has the submarine wreckage, Lighthouse (distant), Eli speeches scattered all over (triggers). A _very_ early draft.
e3_seafloor Sketch WIP, Prototype, sketch A section of cliffs and dried seafloor, buggy as well. Similiar to above, lacks most of the seafloor-level and a bit modified.

antlion_cliff Exploreable area Concept Seafloor level with antlions. Design resembles e3_seafloor. Could be an very early version of it. Cliffs, dried seafloor and antlions. Has parts from proto_riverbed.
antlion_cliff1 Exploreable area Concept Seafloor level with antlions. Above map in an earlier form.
antlion_cliff2 Exploreable area Concept Seafloor level with antlions. (still!) No comment
e3_outpost_test Sketch Prototype, concept Wasteland/seafloor outpost. Occupied. Wasteland/seafloor combine outpost. Long traintracks go over it. Player uses and combine APC to enter but is exposed at some point. Has rollermine spawns somewhere.
e3_seacliff Sketch WIP, Prototype, sketch A section of cliffs and dried seafloor, buggy as well. same as in /e3/. Has been worked on more. Has textures on the seafloor now instead of generic dev/measure textures.
e3_seacliff01 Sketch WIP, Sketch Very early E3 2003 seafloor concept. Layout changed. A very early concept on what became the E3 2003 seafloor demonstration can be seen. Still lacks proper road and a lot of stuff got changed later on in the layout.
e3_seafloor Playable map WIP E3 2003 seafloor / coast techdemo/gameplay E3 2003 Seafloor gameplay-demo. A very refined and E3'fied e3_seacliff01. Almost all of this overall concept made it in to the retail, altough a lot was added and changed.
e3_seafloor_01 Earlier version, still has the whole map layout from 'seacliff'-era left as opposed to the stripped found in above. The combine gate was replaced with buildings, one of them is the one where you use your buggy to blast trough a window with a indoor ramp. A lot of this was packed together to keep the map faster-paced and shorter. Train bridge is still taller on this one.
e3_seafloor_02 A lot of the 'not-seen-in-demo' area got trashed for better performance. Bridge redone and buildings relocated to form the basis for the dock.
e3_seafloor_02_ab Triggers, gunship, docks and the roads have been added as well but are lacking wrecked vehincles. Some extra buildings surround the area which got removed. Bridge still taller, why was it lowered?
e3_seafloor_02_ds Same as above, only other half exists on this version. Both have the new style submarine with interior (model instead of brush)
e3_seafloor_03 Playable map WIP, concept etc.. E3 2003 seafloor development stages. Early to the end. Back to oldschool design and layout. Same as the stuff in e3_seacliff and others during that time. Stuff just shuffled around a bit.
hub_test Playable map WIP, concept, prototype Two combine bases and APCs. Antlions & repellants Wasteland/seafloor style with early antlion repellants and antlions. APCs that you are supposed to steal? Gates open and you can continue on. There are two combine bases, a smaller and a larger one.

hub01 WIP, concept, prototype / Two combine bases and APCs. Antlions & repellants Playable map Above but in a different development stage. Ups and downs, not sure if which one is older.
jeep_beach01 big_terrain changed to include a beach and some ships. 90~% dry land.
jeep_jump Playable map Prototype Jeep jump racetrack/Physics test? An totally unrelated jeep test map (more like a set up racetrack). Must have been a boring day since they actually added lots of unnecessary eye-candy ;)
jeep_test_01 Playable map Prototype Jeep Physics test? Done in a same fashion as the above. This one has a huge hill leading to a loop!
proto_bridge Test Prototype Look up proto_bridge. Same old proto_bridge.
wasteland2 Exploreable area Prototype, concept Wastelands and a digger. Same boring wasteland landscape, close to big_terrain in style. Has the digger drivable vehincle !

d1_trainstation_01 Playable map WIP early retail d1_trainstation_01 in it's early days. You arrive in the furthest track and progress in a quite similiar manner compared to the pre-compiled found in the leak. This one has a better looking train but other sections seem a lot more bland. Barney takes you and gives his few lines as a popup text. Last line: "Have fun storming the castle" is unique. Here be the retail trainstation, Much earlier on in development of course ! Seems to have retail citadel in the skybox. Traintracks have been changed to allow a alternate escape route.
d1_trainstation_02 Playable map WIP early retail trainstation_02 & 03, reorganized & merged. Comparing major changes to retail. Start room indicated that this was done after _01 since its more detailed in this map. After the door you are straight in the "pick up that can" section. The large hallway has a straight opening to the plaza. Outside you are called in by a citizen who you follow for a while until he gets busted by the metropolice. The plaza looks a lot more bland. Nice bonus is a subway entrance right away on the left when you walk outside. There is a cafeteria that used to house security equipment that got scrapped in the retail (close to the area where you continue on when you revisit the area (streetwar)). Apartments are moved closer, replaces the place where the combine let you peek a little inside but shun you away immediately. (On the right when you enter the plaza, first underpass) In the apartment there is a chatty citizen (no idea what he says there). An bridge connects the two buildings together (still left in retail, but emepty) The bridge leads to another apartments that leads you to the roof.
d1_trainstation_03 Playable map WIP early retail d1_trainstation_04 mostly. Roof is rougly the same layout-wise. The window you go out from is on the left side instead of going straight ahead. Rooftops are flatter. You use ladders at one point to reach another building. Before the last building, the ledges get pretty slim and requires more concentration. No scene of alyx kicking the combines asses, Instead you progress in the house manually (up and down, forward) Story-wise _01 is recycled and you get a placeholder for the lab (area #2 for some reason, the familiar area #1 is missing completely!) HL1 style placeholder teleporter. After failed teleport (you didn't really think that it would actually _work_? ;)) you venture on with barney trough the traintracks. He ends up on covering your ass while you run for it. Story links> d1_trainstation_04.
d1_trainstation_04 WIP replaces retail 'd1_trainstation_05' d1_canals_01 section but veeery streamlined so a lot of stuff is missing. links to d1_under0102
Watch the E3 2003 demonstrations instead of me explaining the same with words! Some interesting remarks not seen in there will be explained here, ALL are playable and polished snippets which have to be played exactly like in the demo, not doing so will get you stuck very easily.
devtest Playable map WIP borealis in pretty good shape. A one big prototyping map? Later version of nov_borealis. Major additions everywhere and design/quality/era -wise fits in the E3 2003 style. Stalkers, combine, scripted sequences, Odell (placeholder?), Still not the last one.
e3_bugbait Combines bits from 'sawyer/d1_prison_02-05'. There is an altered bathroom area as an leftover, which hints that the entry was altered for e3.
e3_c17_01 Gordon and Barney C17 snippet.
e3_c17_02 Strider C17 snippet.
e3_lab Lab.
e3_traptown Show-off stuff for E3, earlier versions still had that water tank to jump in to. So e3 version was just a show-off mockup. Connections: "d1_town_04_to_03." landmark.
e3_seafloor Has some stuff that hints that the entry used to be where the current retail is. Still has leftovers from early days (Eli speech triggers).
e3_techdemo_1 Face posing (First tech showing with gman speech lipsync etc..)
e3_techdemo_2 Deform, physics room.
e3_techdemo_5 "Stress test" rooms. Interestingly one visgroup is named "05 hydras"
e3_techdemo_6 Docks. Town entry reminds something a bit closer what is seen on the retail. Reuses an wasteland 3D skybox.
e3_under_02 The hydra scene.
testroom_standards Exploreable area N/A Measuring reference. Measuring textures all over, Contains pre-determined values for heights, halls etc.. a consistency reference.
zoo_shader Exploreable area N/A All(?) shaders in various rooms. Shaded stuff! If you want to see a plethora of different shaders then check this one out.

proto_trainstation Sketch WIP, sketch Trainstation draft with some canals thrown in. There is a canals section hidden. It's the one with the three tar/water jumps that throw you down. The whole section has some detours/differences, used to be more complex in a way. Draft on the first few maps. Trains are tram models. You can access the whole station since nearly all the barring walls are not there! Plaza metro stairs are in a different spot.

MAP NAME .VMF What is it State or purpose What does it have Comments
d1_town_01 Playable map WIP Very good progress on ravenholm (maps order got changed) Town map, dev stage is approx. in E3 era. linked to from canals. Has much of the retail features but starts straight from the second ravenholm map (no outdoor grassy area first). Suprisingly much has been laid out in hammer and a lot of the stuff are very close to the final iterations layout/concept/idea-wise. Just lacks the polish.
d1_town_02 Playable map WIP Caverns section, still work to be done. Gameplay is there. The caverns entry/main room as seen in the end of ravenholm. This has a headcrab generator/mother/whatever blocking your path. You need to get up and get the digger, blast away some barriers and then use it to kill the generator (termorarily a combine advisor model). Elevator takes you up to the d1_town_03 (strangely landmark says that this is _03 and the next will be _04, leftover?)
d1_town_03 Non-traptown version. Further work done. Has the second area which is largely different to retail and different progression. in same style as _05 WIP very close to '/aaron/d1_town_03' No refereces to the cavern-version of the map.
d1_town_04 Playable map WIP Traptown and _03 mixed together, no combine elements. A mixature of _03 and the e3 version! Starts where the retail does as well and has the previous sections removed. It now links to 'town_03_gameplay'. Still has the water tank instead of combine.
d1_town_05 Playable map WIP An early retail area. (available as map source from valve) Linked from _04. The main area of ravenholm (The one which is available as an official map source) Early version of it (Oh, wow.) Progression is same to retail. End links to _04 as well ! Contains both maps (_04 and _05). The _04 progression is different since _05 is thrown in at a different time.

MAP NAME .VMF What is it State or purpose What does it have Comments
coastline_bridge Playable map WIP Coast bridge map (pre-sandtraps) The big train bridge from retail. This one has a regular road instead of the traintracks. Most of the basic layout/gameplay is there, but lacks the detail completely. Other side of the bridge reveals a unused road that got scrapped. Bridge mid-sections used to have some generators instead of random shacks found in the final.
coastline_cliffside1 Exploreable area WIP, concept Coastline with a road. Very early stages of dev. Very early draft on a road along the coast. Seems a bit familiar but I can't pinpoint the counterpart from retail.
coastline_cliffside2 Exploreable area WIP, concept Coastline with a road. Very early stages of dev. #2 Same as above, this section resembles the section from retail where you first meet rollermines with your buggy. (After some tunnel?)
coastline_lighthouse Exploreable area WIP, concept Coastline with the same style as above. #3 A bit same layout to above. Has a lighthouse brush (model look-a-like) near the end.
coastline_map01 Exploreable area WIP, concept Coatline maps as a whole in a scale model! A layout of the whole coast in a scale model! Will help if you want to piece these maps together. (Has borealis??). Ends in a prison (no bugbait puzzle). Detail is very rough and blocky. Lots of stuff can be found like the e3 section hidden away a bit from the rest.
coastline_prison Exploreable area WIP, concept The last coastline map, ends in a prison and has borealis? 90% same as in the _map01 blueprint. Only two borealis clones have been added (with a less bright colour)
coastline_warehouses Exploreable area WIP, concept One of the first coast maps. Houses, same as above, can be found in the layout. Strange that it has some docks.. (Not similiar to the ones in the first retail coast level)
d2_coast_01 Exploreable area WIP, concept First coast map (same gameplay as retail) Very early design of the first coast map (first in retail as well, you get the buggy in here). Has all the basic ideas, get buggy, progress higher and jump over a bridge.
d2_coast_02 Exploreable area WIP, concept Second coast map (rougly close to retail) A bit more detail than above. Has a small combine outpost near the end and the submarine makes an appearance! No roads to be found.
d2_coast_03 Sketch, playable map WIP Third coast map. (Pretty close to retail overall) Un-E3'fied seafloor. Lacks the lighthouse and Some other stuff as well. No clear entry, could be that player used to enter from the lowest level? _02 ends so.
d2_coast_04 Exploreable area WIP, concept Fourth coast map, got reworked in the end. Very early draft on a road along the coast. Section is not familiar.
d2_coast_05 Exploreable area WIP, concept Coastline with a road. Very early stages of dev. Very early draft on a road along the coast. Seems a bit familiar but I can't pinpoint the counterpart from retail.
d2_coast_06 Playable map WIP Coastline bridge map, newer than 'coastline_bridge' An extended version of 'coastline_bridge'. Visgroups reveal an older iteration of the brdige! Early 2001-2002 syle design with brush based architechture and blurrier textures.

d3_borealis/

A close to 'devtest' stage of development on borealis. Cut in to parts to help the performance and loadtimes since it is getting pretty huge and complex at this point.
MAP NAME .VMF What is it State or purpose What does it have Comments
d3_borealis_01_006 Playable map WIP Borealis 1/3th, "Backside". similiar to 'devtest' The side opposite to 'devtest' start is playable in here. This time around it contains more stuff and doors. Links to d3_borealis_02 and d3_tug.
d3_borealis_01_008 Start area has been isolated away, rest is missing.
d3_borealis_01_009 Exact opposite.
d3_borealis_01_017 Playable map WIP Not much has changed except the start and meat room. All back in again, stuff removed from the start. Meat cooler room has been blocked (only available via visgroups!). Small changes everywhere.
d3_borealis_02_001 Playable map WIP Borealis 1/3th again. "Middle". View to the sea (pieces of ice floating). Lacks Odell and has some combine-like structure inside a few rooms (breaking them). Inside there are a few female assasins.
d3_borealis_02_002 More detail again, fridge area has been done better.
d3_borealis_02_003 Playable map WIP Not much has changed. Some stuff in the fridge backdoor.

d3_borealis_001 Playable map WIP No comment No comment.
d3_borealis_04_001 Playable map, sketch WIP start from 'devtest' and stuff from _03_ 'devtest' but starts from the inside instead. Gets cut when you to lower floors. Middle outdoor from _03 exists also.
d3_borealis_04_002 Above. WIP No comment. No comment.
d3_borealis_05_001 Playable map WIP Engine rooms from borealis. This time around we be having combine in the engine rooms. Engine rooms have new model syntax as opposed to _01_ maps. Blood and violence ahoy!
d3_borealis_05_005 Playable map, sketch WIP Afrer the engine rooms, last parts. This time around we focus on the last two hangars before escaping on the tugboat. Not much to see, old engine room can be found behind the level changing triggers.
d3_borealis_06_001 Playable map, sketch WIP parts from _02_ combine wierd thing from _02_ and the meat room.
d3_borealis_07_001 Playable map, sketch WIP Borealis deck and hangar. Player outside in the front, entry is done where you exit the ship approximately. Continues on to _06_.

dario/

MAP NAME .VMF What is it State or purpose What does it have Comments
borealis_full Playable map (whole chapter in one map) WIP Full borealis from 2001. Wierd mixature when compared to d3_borealis. Has pretty early design and architechture (not same as nov_borealis). More polished than 'd3' but lacks a lot of detail and stuff that was added later. Area of coverage is comparable to 'nov_borealis' or 'devtest'. Must be a show-off map due to all being together in one map (slow as hell).
borealis_full_untouched Same as above. WIP Full borealis from 2001 again. Largely the same, has two visgroups which clip eachother a lot. Lacks the surrounding sea and stuff.
c17_archetype Playable map(s) WIP 'd4_streetwar_01' with a big overhaul. Loosely based on 'd4_streetwar_01'. Much further on with development, has multiple areas which are not connected together, worth a check if you want to see an early'ish streetwar. Ends on plaza.
c17_assault1 Playable sequence Prototype Building ambush / assault map. One of the buildings found in above map, earlier designs. Contains a few floors and you + the AI are ambushing it. Attic has a few weapons.
c17_assault2 Playable sequence Prototype Plaza ambust / assault map. Same idea as above, this time you are assaulting the plaza from 'c17_archetype'.
c17_test1 Playable map WIP Streetwar streets and the courtyard. Streetwar streets. One of the unreachable areas from 'c17_archetype'. Has the 'proto_c17courtyard' section merged in with gameplay modifications and some textures. Ends in combine walls.
d1_town_01_dario Playable map WIP Minecart ravenholm, done before 'd1_town/d1_town_01' earlier and different from 'd1_town/d1_town_01' Has the old minecart progression/puzzle. But lacks a plethora of other puzzles introduced later on. Has a few maps merged in but it is still a lot more linear (lack of puzzles) compared to what it is later on. entry is done the oldschool way from the road and you enter the building via a hole (same where you start from in d1_town_01). Lot's of other stuff that was cut can be still found in here. Really worth a check if you want to see original ravenholm stuff but still want it to be in a good shape.

streetwars01 Exploreable area Concept Old streetwars style map. Linear and seems to be a mockup. Oldschool 'brush 17'. Linear street that forks in to two for a short period. Seems to be a mockup.

airex maps have LOTS and LOTS of stuff hidden behind visgroups, be sure not to enable all at once! (lots of old stuff will clip / collide with new stuff). All maps have lot of them laid out but are very crudely done. I'd say that these maps are from 2001-2002, One could take this all and have enough to go with to faithfully finish what valve didn't. Remember that nearly 90% of what you see are placeholders.
MAP NAME .VMF What is it State or purpose What does it have Comments
airex_0102 Sketch WIP, concept Airex 1 and Airex 2 in one map. Allright, this level is so huge content-wise and the map screams like a detuned violin. Insane amount of stuff hidden behind visgroups.
I suggest you take a look on some airex mods to see this better. Listing more than this in here would be just insane. Last areas remind of citadel and EP1 in some sense.
airex_03040506 Sketch WIP, concept Airex 3/4/5/6 in one map. The rest, Split in to three areas by visgroups. Core interior/exterior and surroundings. Refinery & surroundings. Has some old fan+wind puzzle in one group. So much to see in these both!
airex_rough_puzzles Test(s) Prorotype, concept Various puzzle candidates in visgroups. Puzzles for airex, rough drafts hidden in visgroups. Pretty interesting stuff to avoid, one in particular reminds me of the EP1 "combine energy ball in a shaft" puzzle.
airex_start Sketch WIP, concept Airex start Basis for the starting section. You smash your way in to the air ducts. Visgroups hide some stuff seen on the above maps.
d1_tempcanals_01 Sketch WIP Slightly reworked 'bastille' A section familiar from '/aaron/d1_tempcanals_01'.
d1_tempcanals_02 Sketch WIP '/aaron/d1_canals_02' with some wierd 'd1_under_04' links A cut version of '/aaron/d1_canals_02' For some wierd reason the hangar area has two entries/exits to 'd1_under_04'. You had to go trough an under section. Maybe to open some gates?
d1_under0102 Sketch WIP 'aaron/c17_canals/d1_under0102' a bit cut. A section from canals ase seen in '/aaron/c17_canals/d1_under0102' (In a bit? later stage.)? Visgroups reveals the 01 OR the 02 map. Also hidden away is a very early canals design!
d1_under0102a Manhack debut area from _02 visgroups isolated and some stuff worked on.
d1_under0102b Some layout changed, rest aside from 'manhack debut' has generic measure textures applied. A bit more brushwork and detail on _02 areas. Most of the changes is where the 'water mixer' is in final.

_01 area: Quickly scrapped entry, school bus(!) entry is done in the same way as seen in '/c17/proto_trainstation', actually very similiar with a lot more detail of course.

d1_under0102bbbb Opened some areas up, 'water mixer' area reworked again. Other layout changes on 02.
d1_under0102bbbbb 01: Changed the 'drop in to' tunnels a bit. 02: Pipe extended and the level is now finishable.
d1_under0102bbbbbb 01 has some wierd modifications that make it almost unfinishable at it's current state. 02 does not exist. 01 has grey measure textures all over it.
d1_under0102bbbbbbbb Clost to above in 01 part. No more "drop in" entry. Bus is cut. 02 has some missing brushes, likely due to changes. Pipe has some changes and cosmetic background where it ends. Minor details.
d1_under0102new Playable map(s) WIP Under 01 and 02. Seperated by visgroups. Pretty close to 'd1_under0102'. Some stuff changed and added. Some metal doors added and textures here and there. 01 starts from the slide down to the open area in canals. Then goes on to a door that takes you to two slide-traps. You move on to 02 which has some changes done. Citizen 'joe' is the one getting killed by the manhacks. Ends near the manhack room (flooded in retail) You get a peek of canals in the end (moved away from 01). Continues on further 'under'
d3_under0102 Playable map(s) WIP Under 05 and 06. Seperated by visgroups. Again the: "Let's hide random stuff behind visgroups" -day. Just the hydra gameplay levels :) Yes, you heard that right! Hydra in a non-e3 enviroment and as a part of the gameplay ! I will explain these as visgroups since this map basically tells a lot on the hydras.
VIS #2 Various hydra encounter prototypes. Rooms with a circular shaped hole (similiar to the tentacle monster in the first game) Other gameplay stuff here and there.
VIS #1 #4 #5 #6 A section linked from 'd1_under_04'. Starts off with stairs that lead to a sewer tunnel. After a few turns you end up in something that resembles the citadel entrance chasm / digging site. Crossing the wooden planks to the other side will lead to another tunnel. Interesting fact that combine walls can be seen above, but what you are going under in to isn't the citadel! It is the Depot model! In the tunnel you will find a small hole, dropping down from it will throw you together with multiple hydras and some combine. (after defeating?) will get you access to level change.
VIS #3 #8 #9 You continue on from the hydra introduction scene to a huge drop in to the water. Area looks pretty original (close to stress test designs). The whole area is Pretty well done since it has models, gameplay, textures and stuff. Progresses on to a bridge that takes you to a larger sewer area. After a while you will meet npc_hydras. Later on you will reach an another hallway that takes you to.. Stress test start! This is what the original purpose of that elevator and shaft is!. Links to d1_canals_01 for some strange reason. Crazy mindfucks with the progression order, eh? WORTH A CHECK!
demo_matgallery Exploreable area Prototype 'kleiner_labtalk' modified a bit for showoff purposes. 'kleiner_labtalk' in a modified / earlier? form ! Has swappable version via visgroups, Material demo or the real deal. Missing nearly all the detail from 'kleiner_labtalk'. Links to 'subt_01' Instead of the steam map. Mat enabled version is largely the same but with slight changes and mostly a model showoff. All various NPCs scattered around the map. Container in place of the teleport!
e3_techdemo01 Early 'e3_techdemo_5'. This follows the same style that is seen near the end, linear tight corridors with sightseeing on the right. Has foliage and some gman rooms with props. Implemented in 'e3_techdemo_1' later on as a seperate map.
e3_under_02 'e3_under_02' with visgroups mocking at you since they do nothing. See 'e3_under_02' for details.
kleiner 'kleiner_labtalk' with some very slight modifications. See 'kleiner_labtalk' for description.
kleiner2 See above
ms_lab dupe of '/aaron/ms_lab'
proto_underground
proto_underground_combine01 Exploreable area concept citadel<>sewer chasm design/test Early version of the citadel chasm and sewers as seen in 'd3_under0102'. Early citadel designs in a box.
proto_underground_combine01a Exploreable area concept citadel<>sewer chasm design/test Same as above, has a start on the wooden planks that cross.
subt Sketch WIP, concept arcade > lab map. Oldschool c17 design. This helps you to piece the long lab and the arcade together! Underground segment in the style of old c17. Whole map has visgroups that hides some stuff but it's a brushy maze mostly. Check it out!
subtbbbb Sketch WIP, concept d1_under0102 to this one. Takes to _04 Whats up with the naming?. Has parts from above map but implemented as 'd1_under_03' most likely later on in development ! Much of this made in to retail in some form as did nearly all _under_ maps.
temp3 Exploreable area concept airex, earlier than the 'airex_03040506' thing ? see airex maps, so many revisions plastered together with bubblegum that it's very hard to document these properly, yet alone describe them in a way that anyone other than me understands it.

dave/compile_versions

All under maps area finishable. Worth a check since these are one of the best 'new style' under maps found anywhere in this pack.
MAP NAME .VMF What is it State or purpose What does it have Comments
d1_under_01 Playable map WIP 'd1_under0102' seperated. 01 map. A seperated 01 from 'd1_under0102' 01. No other modifications.
d1_under_02 Playable map WIP 'd1_under0102' seperated. 02 map. A seperated 02 from 'd1_under0102' 02. No other modifications.

d1_under_04 Playable map WIP 'e3_under' with no hydra and some other crap instead. See 'e3_under' Everything until the hydra is the same. Hydra area replaced with a large hall that was moved to the endgame in retal (whole map was). Seems that you where supposed to enter this map from the canals huge hangar (see 'd1_tempcanals_02' on previous folder). Has extra visgroups that reveal nothing. Large hall advancement is a bit different since you go down instead of up. This is the hall where you use the cart to get higher. No other hydra references. One tunnel does have vaguely similiar design.
d1_under_05 Visgroups #1 #4 #5 #6 from 'd3_under0102' as 'd1_under_05' . Look those for a description on what is stored in here. Hydras cut. WIP See 'd3_under0102' from the previous folder. Has the visgroups: #1 #4 #5 #6

d1_sewer_steam2 More work done, _04 start area has straight connection to the hall with no staircases in the middle. Details in the hall and some organic looking tubes? added.
d1_sewer_steam05b Details, the level now has a rough draft on the sewer area (after the main hall). Borealis props copied over.
d1_sewer_steam05c Alternte endlevel layout. Has a very early hydra holder as seen in 'd3_under0102' from the previous folder !.
d1_sewer_steam05g to-be Hydra section is now part of the map flow. Changes again the in the areas close to it. Has some wooden plank puzzle added in after the hydra section.
d1_sewer_steam06 Lab's goo pipe textured pipe and an elevator in an isolated area.
d1_sewer_steam06b Sketch WIP, sketch Still and early draft. First iterations of hydra as well! _06 elevator in a visgroup. Lot's of other random stuff overlapping. Visgroups reveal an alternative hydra scene, a bit more refined one still in the same 'tube' style.
d1_sewer_10 Sketch WIP Early iterations on the 'd1_under0102' 'd1_under0102' Likely in it's earliest forms. Lot's of crude brush design and many areas are altered a lot (some are longer and some shorter). Worth a check! Has the busride in visg. and the bus!
d1_sewer_11 Layout changes. early e3 hydra sequence also hidden in visgroups !
d1_sewer_12 No comment.
d1_sewer_13 Texture changes?

d1_sewer_23 Major texture changes and some layout as well.
d1_sewer_25 Another texture change on nearly all. Layout changes and details added as well.
d1_sewer_35 Different section, an early '/dave/compile_versions d1_under_06' Visgroups reveal crude drafts on the map layout. 01 and 02 exist as well. A bit refined (follow along 'd1_under0102' variations).
d1_sewer_36 One curve in the tunnels has been finalized. No longer a brush hell in that section.
d1_sewer_37 No comment.
d1_sewer_41 Extended the sewer area. No real changes to the other areas.
d1_sewer_43 Elevator area added in an early form. Other layout changes.
d1_sewer_44 Some minor layout changes.
d1_sewer_47 Bridge has been wrecked up a tiny bit. Rocks now force the player to take a detour near the 03 start. 01 and 02 are still the same.

d1_sewer_51j Playable map(s) WIP Later iterations of d1_under 01 02 and 03. Changes to sewers (close to the section seen in 'h')
d1_under0102 'd1_sewer_51j' with some more details, nothing major except lacks the 03 area.
d1_under0304 Playable map(s) WIP Various sewer maps punched together to form a progression. An alternate detour to the 'hydra sewers' You start from the sewers near the end of 'd1_sewer_xx' _02 parts. After that you are slapped in to pasted 'd1_sewer_steam' which leads you to a dead end. Does not have much interesting stuff besides being a collage of various sewer maps.
demo_matgallery01 Exploreable area Prototype 'kleiner_labtalk' modified a bit for showoff purposes. Older variation of the same in the previous folder. Lacks the original stuff in visgroups.
demo_matgallert01b Exploreable area Prototype 'kleiner_labtalk' modified a bit for showoff purposes. A bit newer version of aboce.

traps001 Small exploreable area Prototype Three(!!) models laid out in a box. Same as above with a guillotine added in.
zoo_props001 Exploreable area concept Prison-like setting with some props and an outdoor area. Interesting prison-like prop-littered area with outdoor section. Skybox has two tall c17-like buildings. Maybe this was some sort of depot near the c17 exit ? Could just be a test map as well.
