Half-Life 2: Episode One Content
This version of Half-Life 2: Episode One content has been revised and cut out the extra ones that you definitely won’t need. You can use it for a simple game on servers, a single game, playing with friends or your own server.
Content for Garry’s Mod, which contains models, parts and textures from the first episode of Half-Life 2.
If you want to get rid of annoying ERROR and EMO-Texture errors on Garry’s Mod servers, then it definitely makes sense for you to install this content.
There are no backdoors or other "holes"!
