Description

After the events of A Soldier's Tale the Sven Co-op team sent a nuke through the big Race X portal to shut it down with the help of MarphyBlack's squad. Part of the explosion came back through the portal and there were no survivors. Whats worse is that the explosion created a reaction with the portal, disrupting space around it, capturing the ruins of Gamma labs and the sorrounding sectors into a harmonic reflux.
The entire area is now shifting in and out of Xen, and the team is rescued by Luther Johnson's portal device. There is no time to escape the reflux before the area is sent to Xen forever so you must join everyone on a race towards Sector D of Gamma labs where the scientists have set up a working Portal House device to get back to Earth. But it won't be easy.

Additional info

The Portal House map series had a lot of problems, and many servers avoided installing it for several reasons. I wanted to remedy that because it was enjoyable to most people. So I remastered the whole thing.
On top of huge amounts of bug fixes, and file organization, the old story which had default dialogue lines that made no sense at all is now a proper full fledged chapter with sense, themed around the post-Decay events that we never knew: the fates of Keller, Gina and Colette. Join them in this revamped adventure.

NOTE: I didn't bother to properly translate the motd text files much, but anyway nobody reads them

Changelog

+ v3k - Jan 28, 2026 (by Garompa)

A1

• Attempted to fix the invisible truck when it moves on the ramp by adding one unit of offset position
• Mortar was facing the wrong direction, now it faces the correct one towards the tank by turning it into an op4mortar

A1 climax:

• Attempted to make gus not turn around super slowly and breaking some cutscene animation timings

A2

• hecu black beret showed up as military pólice. Changed it so the heads are now random.
• Attempted to fix truck's missing sound when moving
• Batteries can now be picked up again
• Fixed portal sprite, now there is only one portal inside the truck
• Portal in the truck is now smaller so it doesn't clip through
• The truck won't advance past the door until the apache is shot down now
• Unusable elevator buttons are now buttons instead of doors
• Ammo sprite missing from ammobox is now back in

A3

• Resized skybox entities so they do not clip the map
• Round elevator now has sound and crushes anyone blocking it. Previously it would get stuck potentially.
• Players sometimes started without weapons. Attempted a small fix using player equip
• Players are now respawned atop the tower where the scientists are when spawns change
• hev charger holding the hev upgrade was turned around because of item generic bone controllers. It is now a cycler to prevent this and is now solid 0
• dr.ben might get stuck when running, added a monsterclip until he has to run and a teleport to the door he opens after a few minutes just in case
• game text says misión instead of mission. Fixed.
• jbarn, xonxt, ben and kate walk instead of running to the lab, taking ages. Fixed!
• final portal cutscene takes too long, npcs keep walking. Now all npcs run around the lab in their sequences

A4

• Invisible weapons at the spawn of the office now have a visible ammobox to make sense of it
• Tentacle can be buged and it Will fly upwards. There seems to be no fix for this other than adding a trigger hurt for players under the tentacle and cross fingers.
• Invisible wall in the truck with a turret cannot be fixed, it is part of the map cliphull for players. To make sense of it, the doors close again after the turret inside dies

B

• Luther had the same text color as gina. Now he has the same white text as the first map

C

• conveyor where some alien barrels come from is now additive as the others, with an effect so you cant properly see behind
• race ufo doesnt seem to be attacking with the beam. It was due to poor func tank aiming, probably, and the relations table. It is now a bit fixed and should work a bit better.

D

• cave water is now less additive so it can be actually seen

+ v3j - Sep 27, 2025 (by Garompa)

• Replaced scientist_ben.mdl with a version that has all the missing animations yet again (now 100% fixed, hopefully)
• Fixed and added one more model too, for 3D skies with effects.

+ v3i - Sep 14, 2025 (by Garompa)

Last 2 maps (c and d):

• Added trigger hurt in the Xen section in the first map, which was missing and could get players stuck. If you fall you now die.
• Toned down trigger hurt from 999999 to 11111 to prevent gettin healed instead of damaged.

+ v3h - July 7, 2025 (by Garompa)

Last 2 maps (c and d):

• Reports about the ufo boss getting stuck appeared. Probably was because it spawned outside the map and then was teleported forcefully. Also it might get stuck with the small wall near its spawn area but that cannot be fixed much. So I made the ufo a squadmaker placed inside the map, and the forced teleport is now a changevalue that will edit the path so the ufo flies across that path. I have also put it higher up in the air so it does not get stuck with the small wall as much as possible when spawning and flying.
• The last map had a few issues with the rendering of the manta making it look like it was stuck. It just was visible when it shouldnt have been. The env renders for it and the initial visible state are now fixed and invisible.

+ v3g - July 7, 2025 (by Garompa)

All maps:

• Lose condition npcs now resurrect and don't trigger the map restart anymore
• Lose condition defense objectives like the truck and control rooms now have huge HP pools, but do still trigger map restart. This is because the map would break because of complex triggers if the map didn't restart at this point, but don't worry, I believe 3-25 million hp should be enough, right?

portal_house_a1_r:

• Luther can now teleport using the portal chamber if you want to
• Teleport destination now has a push to prevent telefrag
• Many npcs that spawned infinitely now don't unless its necessary. And those that are necessary now properly get deactivated once the bosses are dead.
• Chairs are not item_generic instead of monster_generic
• Grunts around the apc and truck now spawn from it instead of out of nowhere in the air
• Massns in the elevators now spawn all together. The fight is harder, but there are no spawns out of thin air anymore. They had to spawn together because they trigger things on death.
• Some npcs that didnt have monsterclips now have them properly
• Valemoth now has displayname just in case
• Npcs that spawn from tunnels and such now are moved close to the end of the tunnels and make use of the render effects to spawn slowly like they were hiding in darkness or cloaked
• Xonxt and other essential npcs respawn and do not softlock the maps anymore
• env_xenmakers are now squadmakers and squadmakers not make use of only one xenmaker for the effect. Cyclic and non cyclic squadmaker conversions were adjusted accordingly.
• Some cyclic sqmakers now have cyclic backlog just in case
• Moved some func_wall details that were floating outside the map into their proper positions: the wheels of the very HD heavy door in the secret displacer area that go into the walls. I have to turn 4 of them into func_tanks also so they can be rotated properly. (they wont shoot, its just props)
• The bombs do not trigger the map restart, instead now they kill all players and explode all vehicles in the car park. And can also kill npcs that get hit.

+ v3f - April 19, 2025 (by Garompa)

All maps:

• Kept fixes from v3e
• Fixed missing crosshair in the weapon_m16.txt for the m41a replacement
• Made big props and 3D skybox models have huge clip boxes so they can render at any camera angle (no more model popping)
• Fixed the probeboss.mdl (the UFO Boss) hitboxes to be in line with monster_apache hitbox numbers, so now it is not all armored and easier to kill without the gauss gun

+ v3e - April 7, 2025 (by Garompa)

All maps:

• Kept fixes from v3d

portal_house_a1_r:

• Made the garage chainlink fence door behind the truck at the start of the first map have Only Trigger flag. Previously players could break it and this was not intended.

+ v3d - Dec 30, 2024 (by Reuniclus-579)

All maps:

• Kept fixes version v3c by Garompa
• Fixed camera and some small details

portal_house_a1_climax_r, portal_house_a3_climax_r:

• Fixed ambient_music

portal_house_a2_r:

• Fixed alarm sound

portal_house_b_r, portal_house_c_r, portal_house_d_r:

• Fixed boss teleport bug(use trigger_setorigin to teleport boss)

+ v3c - Dec 26, 2024 (by Garompa)

• Attempted a fix on changelevel votes before a climax map in case the votes don't go through
• Fixed the bomb secret with the shortcut in the map a1 near spawn (careful! it will blow up the fence AND YOU!)
• Replaced in a1 the invisible wall over the tunnel with some vents and chainlink fences
• In map a3 and a4 all scripted sequences are now uninterruptible and repeatable. Hopefully this fixes most of the npcs but its not fool proof

+ v3b - Dec 20, 2024 (by Garompa)

• Updated scientist_ben.mdl to have all the necessary animations

+ v3 - Dec 20, 2024 (by Garompa)

• Fixed servers crashing due to overflows because of squadmakers that spawned weapons and ammo with infinite spawn count. This was an oversight I didn't check, never imagined the author would do such a thing. (Thanks Nevermore2790 for reporting this)
• Fixed several weaponboxes not being invisible for the big ammoboxes respawning ammo
• Replaced the really tiny and low quality blue xen sky in the last map with a high quality remake, brought by Reuniclus

+ v2b - Oct 23, 2024 (by Garompa)

portal_house_d_r

• Stopped the music once the final scene plays
• Fixed colette and gman not duking it out because of the prisoner flag
• Fixed Keller not having a name

+ v2 - June 4, 2024 (by Func_YE)

portal_house_a1_r

• Fixed the elevator problem.(Although not a perfect solution), the npcs will be pushed with a trigger push when elevator is activated.
• Players can't exploit shortcut points and pass through them
• Players that attempt to bug the tank by standing on it will die now

portal_house_a2_r

• Fixed weapon_vulcan ammo (weapon_vulcan ammo is ammo_highpowerblaster, not ammo_556)

portal_house_a3_r

• HEV modification room fixed. The glass has proper transparency and your suit doesnt get weaponstripped anymore
• Fixed the end button being able to be pushed behind a wall
• Fixed the first spawn

portal_house_b_r

• Fixed the issue where all bosses could be attacked directly if players exploited jumping

portal_house_c_r

• The train won't be able to be used by players anymore

portal_house_d_r

• Barricaded all areas with func_wall_toggle to isolate them, and the func_wall_toggle will be removed when the area is activated. This stops players from outside the areas to jump and exploit the map entering a locked area

+ v1g - June 1, 2024 (by Garompa)

• Gave the elevator in map A1 infinite crush damage so Xonxt can die if he gets stuck in them.
• Gave all maps npckill 2, now they cannot be interrupted with friendly fire
• Added more ammo for the vulcan in map A2
• Added a failsafe for the HEV pickup in map A3
• Fixed the unused camera triggers in map A4, now they don't trigger again the shields and sprites creating problems
• Moved the Target sprites in map A4 to disappear when the objective is complete and target is destroyed
• Lowercased a few sprites that needed it
• Resguy FAILED. Added the missing skybox textures and included it in the res files
• Fixed wrong monster_ entities in squadmakers in all maps (babygargs and gargs)
• Fixed squadmakers' spawnflags in all maps
• Added failsafes to some game_counters, specially the one in map A2 for the bridge lowering

+ v1, based on original v2022 - May 29, 2024 (by Garompa)

• Standardized view model hands with Sven remappable hands, reducing custom weapon models to one set and shrinking folder size.
• Removed spaces from filenames and edited their references in the maps
• Upgraded all NPC models to HD versions, fixing bodygroups, textures, animations, and improving enemy display names and model references. And gave some a bit of spice with also a couple of extra custom models from the default folders.
• Eliminated redundant models and bad references, reorganized .gmr and deleted now useless.gsr files
• Moved all .gmr and .gsr files from the worldspawn to the .cfg files
• Fixed .cfg files to prevent forced map changes, removed timelimits
• Renamed maps with a _r suffix and also moved all files to a different folder, for compatibility with the original version.
• Lowercased all files
• Translated all texts to English, including the textures.
• Fixed critical bugs, including env_beam's StrikeTime overflow crash.
• Replaced floaters with the scripted version.
• Added missing files and removed unused files
• Enhanced gameplay with vote options for climax maps, improved climax start buttons to prevent trolling.
• Added the characters you play as in the original version (Edward Burton and Luther Johonson) as npc allies around the maps, and they still keep their important story cameos.
• Improved truck in map A2: Added a gus driver, enabled automatic movement (you can still move or stop it yourselves), made it repairable (much needed as it was too flimsy), has Edward Burton on the back to help you fend off enemies a bit, The back of the truck is not open (for visual credibility) and it has proper classification so enemies WILL attack it and it is friendly to players.
• Turned target_cdaudio into ambient_music, and added more music.
• Ensured constant HEV suit availability from the first map onwards. And replaced the suit you get afterwards with an in-universe lore suit upgrade and an easter-egg.
• Fixed some npcs classnames or custom model references because they were not using the right model or class
• Improved buildable sentry models
• Fixed an enemy zombie grunt that was friendly in map D, now it is properly an enemy
• Brought back some of the previous versions custom models: todesangst trooper, massn and construction zombie, they at least make a small cameo now
• With the addition of many hurts and clips noow players that try to go out of bounds or walk on the bottom of Xen alive will be dealt with extreme prejudice, and nobody will be able to survive even with scxpm
• Fixed some bugs with triggers not triggering the beginning of map A4 and the heavy door, counters and squadmakers for it (and the Tor). Also fixed the objective cameras with GMan and the Target sprite for the cleansuit scientist boss fight, and the Edward and Gman that never disappeared from the beginning.
• Made several friendly NPCs not solid during cutscenes or train rides and such because they could get the trains or players stuck
• Fixed on map A3 climax some rendermodes on the Xen puzzle that made levers invisible
• Fixed map triggers, improved cutscene animations and timings, and changed most of the dialogues.
• Ensured characters in cutscenes reappearing later as enemies or allies and be witness or executioner of their deaths or whatever happens
• Enhanced intelligent zombie grunts. Previously they were just reskinned grunts, but made no sense that Nihilanth was controlling them, so now they are fully modelled Xen modified crystal headcrabs, and Nihilanth controls them through the crystals.
• Removed globalnames and unused or outdated singleplayer entity leftovers
• Changed info_player_start to _deathmatch
• Added more walls on the A2 map so players didn't rush over the forcefields before deactivating them
• The holograms are all using texture mode instead of additive now (you no longer see the eyeballs floating ha) and they are now prisoner generics, so monsters don't attack them.
• Boosted friendly NPC health, specially the NPCs that reset the maps when they die. (The main defense objectives were not touched so you can still lose the maps if your base is destroyed)
• Stopped a global looping sounds in map B, C and D jesus, made them have long radius instead
• Fixed visible ammoboxes. (may have forgotten some)
• Cleaned up and fixed all weapon and npc scripts, and matched it with the models, sounds and sprites
• Added subtitles to most dialogues.
• Corrected audio issues, including stopping problematic looping sounds
• Cleaned up weapon and NPC scripts, aligned models, sounds, and sprites
• Revamped story elements and changed everything around it. Tried to keep most custom characters intact and worked around that. Iinstead of a story were npcs just say gibberish default lines that make no sense, they now mostly have custom dialogue, and changed around a few npcs as well, and also added a few more. The story now revolves around a post-Half-Life Decay theme.
• Regenerated .res files, and repacked into a .zip.

Dialogue heavy map?

Chimz76 19 Nov 2025 16:22

I'm seeing a lot of dialogue in the screenshots. Do these dialogue sequences stop gameplay and force you to wait until they finish to progress?

Re: Dialogue heavy map?

Garompa 19 Nov 2025 18:55

Some of the maps are cinematic, but skippable. During the non cinematic maps there is not much dialogue at all that and not any that freezes your character that i remember except a couple of cameras that present a boss or something

Re: Dialogue heavy map?

Four-Nines 29 Nov 2025 07:06

don't mind this guy. seems like he just wanna attention since he comments and downvote many maps, lol

Still rough around the edges

loulimi 07 Jul 2025 20:50

I played this map with two other friends. I like the somewhat classic gameplay and atmosphere, with a few novelties here and there, but I felt there were many problems with the map that were not fixed unfortunately: respawning ennemies out of nowhere for instance…

I wrote an article on it (in French): https://mappingfusion.fr/article/portal-house-remastered

4/5, aún con su final... es de mis mapas favoritos para stremear.

monnchips_yt 26 Feb 2025 16:03

Lo jugué con 8 personas en stream, los 2 primero mapas son muy buenos, los 2 últimos no me gustaron del todo. Fuera de todo… de mis mapas favoritos.

Great map series, well remastered

Maathis 26 Dec 2024 14:38

Thank you for remastering the map series. It's an awesome experience. The area in the map is well thought through. It was fun playing. The added content and storyline made a huge improvement.

I noticed some details and issues that I would like to share, in case that someone works further on the map in the future. I emphasize that some issues may not appear generally and are maybe only happening in my case.

General: The level change between a1_r and a4_r does not work always. It gets stuck with a white screen and sound playing normally. Happening mostly when climax is played in between.
The character Dr. Gina is behaving very unpleasant.

a1_r:
- Soldiers get stuck sometimes on the field after descending from the osprey helicopter, leaving the osprey stuck in place too.
- There is an invisible wall above the fence in the tunnel, where the enemy transport tank is. (maybe make the fence higher)
- Do the so-called discovered secrets do anything? This is not clear to me.

a2_r:
Enemies can shoot through the banisters sometimes, although I cant.

a3_r:
At the very end of the map, when Dr. Ben had to push a button for the portal to initiate: Xonx followed into the room and stood in the path of Dr. Ben. He interrupted the process and the map was impossible to finish. Another issue can appear with the soldiers not being able to get into the room atthe end and the map becomes impossible to finish as well.

a4_r:
At the end of the map, it was unclear how to finish at the station. Maybe something is not working quite right? After a while, the map continued.

d_r:
The orange hologram stairs appearing at the end feels out of place. The design does not fit here, or something is not displayed correctly.

portal_house_a4_r MISSION 2: Destroy the Operational Control Center

Func_YE 31 May 2024 16:39

the shieldis not working properly.
fix it.

Re: portal_house_a4_r MISSION 2: Destroy the Operational Control Center

Garompa 31 May 2024 20:31

Thanks for the report, should be fixed now in v1e. The walls were being triggered by a leftover unused multimanager that I restored for the cameras to work. So the shields were working in reverse

Re: portal_house_a4_r MISSION 2: Destroy the Operational Control Center

portal_house_a1_r
NPC : Luther Johnson Phd. or NPC : Xonxt
This NPC sometimes gets stuck in the elevator door. The game cannot continue.(But … it takes a long time for the elevator door to kill him. )
And … I think the server needs to have mp_npckill "0".

portal_house_a2_r
weapon_vulcan no ammo?

portal_house_a3_r
trigger_once -> target : mngr_HEV no work?

Re: portal_house_a4_r MISSION 2: Destroy the Operational Control Center

Garompa 01 Jun 2024 20:48

I have gone and added a failsafe for the HEV trigger. I also added vulcan ammo although that probably was a mapper's decision to not have some. I added npckill 2 to all maps too so there is no friendly fire.

But about the NPC Xonxt, I cannot do much about that, platforms, elevators and doors are dangerous around npcs because thats goldsource engine for you.
Look, if the elevator doors do not have crush damage, they will get stuck even with players. softlocking the map.
Then the author made a super complex thing for something so simple as the elevator, it would be too much of a hassle to figure out and remake the entire thing. So I just added infinite damage to the doors so Xonxt can be crushed easily.

portal_house_a2_r can't stop alarm and can't pull down the brige

NoobLCH 30 May 2024 14:48

Problem happend in a lobby that need to pull down the brige to proceed.
After insert battery and pull down the switch, the alarm up and teleport some enemies. Clearing all eniems(include 2 small things) does't stop the alarm, and brige can't be pull down.
It blocked gameplay.

Re: portal_house_a2_r can't stop alarm and can't pull down the brige

Func_YE 30 May 2024 15:49

squadmaker -> monstertype : monster_alien_babygarg (What is it?)
Original :
squadmaker -> monstertype : monster_babygarg
Use bspguy fix it.

Re: portal_house_a2_r can't stop alarm and can't pull down the brige

Garompa 30 May 2024 18:01

Thanks for the reports, this is serious. A bit of a mistake on my end, and also a bug to report (I hope its fixed someday) to the devs about game counters not working nicely. I will be fixing all squadmakers and adding failsafes to counters. Bear with me

EDIT: Ok, it should be all fixed now!
