Spoiler:The pistol was from Rise Of The Triad. The muzzle flash and third frame of the pistol were shamelessly ripped from Wild Weasel's ww-ana.wad. So was the MP40. All I did was place "Agent Zero" sleeves on it to make it look like BJ's. The minigun was ripped from Wolfenstein 3D Jaguar screenshots I made from an emulator; same with the rocket launcher and the flamethrower.
I will make separate .WADs for all versions of Wolfendoom, since they all use different graphics and such. Right now I'm working on the Second Encounter upgrade.
P.S I know the Gatling-gun is terribly re-sized, I'll worry about that later.
