It is the first game to be released under THQ's 2007 agreement with the UFC, and it is to be the first UFC game released since UFC: Sudden Impact in 2004. A playable demo of UFC 2009 was released onto Xbox Live and PlayStation Network on April 23, 2009, and featured a tutorial and exhibition matchup between Chuck Liddell and Mauricio Rua.

Gameplay
In a contrast to Yukes' pro wrestling games, the new UFC game is described as a realistic mixed martial arts simulator by its developers. Over 100 UFC personalities are featured, with over 80 of them being fighters from all five weight classes. An early trailer from June 2008 showed non-fighters such as broadcasters Mike Goldberg and Joe Rogan, fight announcer Bruce Buffer, NSAC referee Mario Yamasaki, ring girls Arianny Celeste and Edith Labelle, cutman "Stitch" Duran and cornermen Greg Jackson, and Mark Dellagrotte. Models are highly-detailed with over 30,000 polygons used for fighter models.

Fighting styles
The developers at Yuke's Osaka included 6 major primary fighting styles for the fighters in the game; Striking: Boxing, Kickboxing, Muay thai, Grappling: Brazilian Jiu-Jitsu, Judo, and Wrestling. These styles are placed into two categories, allowing a character to have two of these abilities. The "standup" category allows Boxing, Muay thai or Kickboxing, while grappling-style can consist of Brazilian Jiu Jitsu, Wrestling or Judo.

Roster
The complete roster was revealed to and published by GameSpot.

Reception
Initial reviews have been positive with Metacritic giving the game an 83% after 58 reviews and Game Rankings giving it a 84% after 21 reviews. Some reviews cited the lack of a penalty for users who disconnect from online games as a negative aspect, along with lag in online play. Although recently, there has been a patch that must be downloaded, that is preventing "cheating" with the CAF program, by stopping a bug that players were able to exploit an error in the CAF system, that allowed artificial "pumping up" of the CAF's ability meters. 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. According to NPD figures, UFC 2009: Undisputed managed to sell over 1,000,000 units in its first month. 679,600 of these sales came on the Xbox 360, with 334,400 coming on the PlayStation 3.Hyper's Daniel Wilks commends the game for its "very deep, intricate fighting system [and] balanced striking and ground game." However, he criticized the game for its "very steep learning curve, very niche appeal".At the 2009 Spike Video Game Awards, UFC 2009 Undisputed was named the Best Individual Sports Game.
