A playable demo of UFC 2009 was released onto Xbox Live and PlayStation Network on 23 April 2009, and featured a tutorial and exhibition matchup between Chuck Liddell and Mauricio Rua.

The developers at Yuke's included 6 major primary fighting styles for the fighters in the game; Striking: Boxing, Kickboxing, and Muay Thai, Grappling: Brazilian Jiu-Jitsu, Judo, and Wrestling.

The "standup" category allows Boxing, Muay Thai or Kickboxing, while grappling-style can consist of Brazilian jiu-jitsu, Wrestling or Judo.

This patch is also supposed to be able to track those players that disconnect in an attempt to falsely prevent losses from showing up on the CAF's Win–loss record.

It is also supposed to try to prevent lag issues, by matching up players with similar connection speeds.
