Changelog

Community edit:

+ v1 - June 15, 2026 (by Garompa)

• Turned all sound files into .ogg, saving tons of filesize
• Reorganized all files into new folders (it was very chaotic before)
• Merged external mdl files
• Fixed fast headcrab model, adding a death animation and making use of the hl2 animated version (the best one so far)
• Fixed soundlists for many npcs
• Added missing files for many things, like models, sprites, sounds
• Gave weapons with sven arms color remap textures
• Removed duplicate skybox, models, sounds and sprites. Only one copy of each is now used, and the default files were deleted, making use of the defaults when needed
• Removed default keyvalues and unused keyvalues from entities in the maps
• Added more and fixed spawnpoints
• Edited lots of entities to make use of the changes so far (models, soundlists, etc)
• Fixed some file paths resulting in missing models, sounds or sprites
• Enhanced some entities so they work better or look better (position, angles, classname, and other properties)
• Improved the maps logic in some places to prevent any problems with map progression
• Updated scripts and added them to the cfg files. This also meant updating weapon entities in the maps with the new classnames
• Improved cfg files so they make use of everything so far
• Some models or soundlists were replaced with improved versions (e.g. hl2 battery now has glows)
• Merged external model sequences and textures
• Fixed many rendermode additive textures to texture mode so they don't glow in the dark (for glass, water, and things like that)
• Many sprites were fixed to have proper vp_type according to necessity (mostly upright parallel for fire sprites)
• Extracted embedded textures into a new wad file to save filesize with shared maps in the long run
• Updated weapon scripts with latest version
• Removed embedded textures
• Generated new .res files
• Packed into a zip for servers

Possible Progression Bug?

mauricioozaki 26 Jul 2026 22:29

I'm not sure if I did something wrong or if this was a bug, but I noticed some strange behavior.

At the start, we were facing a closed door. To the right, there were two counters and what seemed to be an invisible door. Two Combine Hunters spawned, and during the fight, the invisible door suddenly opened. We continued, fought Evil Father Grigori, and the map ended.

I thought the map would be longer because of the screenshots. Afterward, I noticed that the closed door from the beginning actually leads to another area full of enemies, but it never opened during my playthrough.

I checked my installation, and everything seems to be correct. My guess is that one of the Combine Hunters somehow crossed the invisible door and triggered it to open, causing the rest of the map to be skipped.

Could you please check if this is a known issue?

Thanks

P.S.: I tried playing the map again to reproduce the issue. This time, I spawned in the cabin instead. Two Combine Hunters appeared, and after I killed both of them, the progression got stuck. Nothing else happened after that.

In summary: I think there's an incorrect spawn point near the boss area, and at the beginning (at least in my playthrough), I couldn't trigger the trapdoor in the floor to open.
