Rick Johnson of Raven spent a chunk of time demoing SoF for me, showing me the features of the game. Soldier of Fortune is running a highly-modified Quake II engine, using Raven's own model system. Today they were showing a single-person mission that involved clearing out punks from a rail station, then getting on a moving train to disable a nuclear device. Tomorrow, Rick said, they'll be showing deathmatch. Rick said the minimum system was a PPro200, 32MB, Voodoo 1.
Hardware acceleration is required.
The major attention-grabbing thing in SoF was, frankly, the animations for the other characters on the screen. Nice modeling, very detailed skinning. Shoot a guy, the wound appears and a minor gout of blood comes. Rick shot a guy in the leg, he grabbed his leg and hopped around. Shot another baddie in the crotch, and he screamed in a much high higher pitch and dropped.
