I like making (modifying) models for the HL2 source engine, which is what I spend most of my time doing. I like to play multiplayer games on steam, some of the games I play: Call of Duty: World at War (Zombies) Call of Duty: Black Ops Obsidian Conflict (HL2 mod) Garrysmod (to make gmod poses, or test models)
FPSbanana AR15 model, downloaded it, decompiled it, re-sized it for HL2 standards, made it into a world model, made bodygroups for the sights, fore-grip, silencer and mag, and a skin. Basically turned it from a replacement into something that's better suited for posing in gmod.
