THQ’s ‘UFC Undisputed 2009’ was one of the surprise gaming hits of last year, selling in excess of 3.5 million copies.  As we reported recently though, sales of the 2010 edition have not seized the buying public’s attention in quite the same way.

According to the new edition sold 413,400 copies in May on XBox 360 and Playstation 3, compared with 1,014,000 copies the previous year in it’s opening month.

Despite the lower than expected sales figures the UFC Undisputed 2010 title was still the third biggest selling game of the month behind the ultra-popular Red Dead Redemption and Super Mario Galaxy 2.

THQ will be hoping that this weekend’s UFC 116: Lesnar Vs Carwin event, which is considered to be the biggest MMA event of the year, will help to boost figures, particularly as Brock Lesnar is the cover star of this years game.
