Half-Life: Source

Development Info Bugs Environmental Map TexturesYou got your Deathmatch Classic and Team Fortress Classic in my Source engine! Unused Skybox TexturesThe game contains textures for every skybox from the original Half-Life, Team Fortress Classic, Deathmatch Classic, and Counter-Strike. However, only the regular daytime desert skybox from the original game is used. Unused TexturesA whole heap of unused and pre-release textures in one sub-page. Also, The return of the Headcrab's rear end textures (NSFW Warning).

Unused Content from Half-Life#

All of the unused content from the original Half-Life is still in this game. Apart from the Construction Worker, Antidote and Security Card models which weren't ported over and potentially some other content too.

Fanmade HD Content#

In 2013, the support for the HD content pack included with Blue Shift was added in its own folder (hl1_hd). However, Valve had used a fanmade port of the pack that included some fanmade content instead of the official content created by Gearbox.² Several textures in the HD pack are fanmade, such as the ones for the viewmodel hands, and contain signatures for A. "Stone" Denisov, and there are also several custom models for NPCs. The original mod version of this HD Pack also included various HD world textures in it, something that Valve removed with a patch when it was originally added to HL:S.

Unused Models#

Alien Grunt Gibs#

The game contains a model called "agrunt_gibs1.mdl", which is a piece of an Alien Grunt. This model does not appear in the original game's files.

Rats#

Due to an error with entities, the model for rats "bigrat.mdl" is rendered unused by accident. In the original game, rats appear at the Hazard Course.

Unused Animations#

As this game was just a Half-Life port to the Source Engine, the death animations for all characters go unused because Source uses ragdoll physics instead of pre-made animations for NPCs dying.

Hidden Log File#

The root of hl1_pak_dir.vpk contains an unused log. It is dated to September 25th, 2004 and mentions running an "unusedcontent.exe".

Unused Map#

devtest.bsp is an unused map meant to test how the original game's features would work in the Source engine and are left over from a prototype leaked in 2003 (HL1-ports). This map features an abridged version of the singleplayer campaign, with the Resonance Cascade happening earlier.

One thing to note is that the map attempts to transition into hl1_devtest02. This map does not exist.
