Garry's Mod, the Half-Life 2 addon, has a giant fanbase surrounding it that create tons of custom models, textures, and other things. It was actually through a combination of Garry's Mod and my copy of AVP2 that I intended to put together sprites for the alien drone I wanted to add into FoT.
This entire situation raises a possible question...
Should we try to make fallout sprites from the near-endless available resources in Garry's mod?
I don't know about you guys, but having one of these, or a Combine enemy soldier / recruitable team member would be pretty badass. Those two aside, there are so many possible additions seeming to really benefit FoT that it needs consideration.
