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
