As debuted on SpikeTV Friday night, here’s the first gameplay trailer for the UFC’s new PS3/Xbox 360/etc. jammy-jam, featuring Rampage vs. Forrest, and commentary by Joe Rogan and Mike Goldberg. According to a preview on IGN:

There’s no HUD or health bar, so fighters don’t get worn down till they’re eventually tapped out or KO’d. A fighter can be finished at any time, depending upon the situation. On the other hand, there are more defensive moves and blocking and countering in the game, with a design more similar to traditional fighting games than old MMA or wrestling games. THQ specifically stated that “…button mashing will make you lose.”

Furthermore, the happenings of the fight actually have an effect on fighters during the fight beyond simply wearing them down. When Rampage used punches to the body to weaken Forrest, purple welts similar to what was seen on Liddell’s body when he fought Keith Jardine appeared near Griffin’s kidney. A small cut had formed over the former Ultimate Fighter’s eye, while Rampage had his left eye nearly swollen shut by a series of excellent Griffin knees. All the injuries looked authentic, but also affected how successful each fighter was at accomplishing what they wanted to as the fight wore on.

Reportedly the game will feature an 80+ fighter roster — which still doesn’t explain how War Machine and Saunders made the cut.
