THQ has launched a UFC Undisputed 3 demo and a trailer showing off the game taster.
The demo's downloadable now from Xbox Live (worldwide) and the PSN (US only, until tomorrow), ahead of the title's Xbox 360 and PS3 release on February 17.
It'll let players engage in a fantasy match-up between current UFC light heavyweight champion Jon Jones and current UFC middleweight champion Anderson Silva, and relive a classic Pride mode rivalry between UFC fighters and former champions Quinton 'Rampage' Jackson and Wanderlei Silva.
The playable demo will also offer mirror matches, letting players face off against friends or opponent AI as the same fighter.
The full game will include over 150 fighters across seven weight classes.
