The demo for UFC Undisputed 3 is now available for download on the Xbox 360 (can be queued up here) and has since arrived on the PS3 as well. It features two different matchups that run just one round – Jon Jones vs Anderson Silva under standard UFC rules and presentation and ‘Rampage’ Jackson vs Wanderlei Silva in Pride mode. Leave your thoughts on the demo in the comments and look for videos and impressions later in the week!
