Boxing? Wrestling? Those are easy games to make compared to a mixed martial arts (MMA) affair, which blends both of those sports with judo, karate, jujitsu, and any number of other methods of beating one's ass to a pulp. But THQ's making a fresh start of it with UFC 2009 Undisputed, thanks to a new engine and physics system. Gone are the days of arms that miraculously punch through torsos thanks to dodgy collision detection; with every hit in Undisputed, you'll see flesh deform and bruises form in real time - with no canned animations - at 60 frames per second. The presentation is done slick TV-style; you just happen to control the fight you're watching. THQ is confirming only a handful of fighters (Georges St-Pierre, Quinton "Rampage" Jackson, Chuck Liddell) from the 80-odd final roster, but the ones OXM saw looked alarmingly realistic at 30,000 polys each, right down to the blood spatter and sickening bruises.
