UFC 2009 sells 3.5 million

Anyone needing further proof of mixed martial arts' popularity got a reminder today. THQ announced that UFC 2009 Undisputed has hit another sales milestone, having sold more than 3.5 million units worldwide to date. Developed by Yuke's (WWE Smackdown), the T for Teen-rated game was released last May for the PlayStation 3 and Xbox 360.

To mark the occasion, THQ revealed that Microsoft has now added UFC 2009 Undisputed to its Platinum Hits Xbox 360 collection, with Sony also designating it a Greatest Hit on the PS3. The move means that the ultimate-fighting sim now costs just $30 on either console, half of its original $60 price point.

UFC 2009 Undisputed has been a breakout hit for THQ, which credited it for helping the company reach record revenues last July. During its debut month, the game sold 679,600 copies on the Xbox 360 and another 334,400 on the PS3, topping the 1-million-unit mark in a matter of weeks. (Handheld and Wii editions are planned for this year's sequel.) Critics also responded warmly to the game, as evidenced by GameSpot's video review below.
