With the UFC undisputed 2010 demo being released exclusively to Undisputed community members, and the full game release only weeks away, THQ has dropped a new trailer of a roll call of the full list of fighters. Check out below.

Look for the full game May 25 for Xbox 360, Playstation 3 and PSP. To try the demo you must register here at the UFC Undisputed 2010 community.

For exclusive TUF characters you will need to pre-order your game from Gamestop.com, or at your local Gamestop retail store. For exclusive legendary fighters and fight modes you will need to get the PS3 version, which also includes a free blu-ray of the top 10 best fights of all time in UFC history. If you are looking for a deal on the game, you’re going to want to go to Dascheap.com as they have the lowest price on the net for it.

If you are having a hard time deciding which one to buy here is a comparison of PS3 vs Xbox 360 to help.
