Citizen-132 has done it! We recently got our first weapon, the UMP, into HL2. It is modeled, skinned, animated, has custom hands, and its IN one of our maps.

Credits for these two shots go to:
The map and textures were all by Boxy
Animations and the Hand model by Pariah
The UMP Model and Skin by KingKong
All Code done by Epit0miz3

We hope you enjoy!
