Half-Life: Source Enhanced is an HD replacement pack for the default Half-Life: Source content. This includes models, materials, and map textures. Not to mention the other content that is also released in this mod.
This is a weapon from the variation folder that was added recently.
Yeah, as the description says for the mod, you can change which variations of npcs, models and stuff like that you would like in-game, which is really cool, I dont like this gun as such, but I like the good old SMG from original half life and also I like the look of the smg for half life source HD download.
I like the g36c i just wish there was an hgrunt model that used it, because i hate them holding m4s, then dropping g36c's when they die!
