I'ts a Doom gameplay, playing with Ultimate Super Doom 3 mod, made by Doomero, and Dark 7 MPK map pack, made by Bryant 'Gunrock' Robinson. Dark 7 MPK was modified to run with USD3 without conflicts.
Map: "MAP06 - Final Installation"
(This map is VERY similar to "Bunk1 - Ammo Depot", a Quake 2 map)
Players in this video:
-Doomero or redield21 (USD3 author)
-Diegomula (me)
