For a game that was received so poorly by critics, reaching more than one million sales in such a short time is quite an achievement and goes to show how strong the 50 Cent brand is, especially in the US, but also in the UK.

"The exciting convergence of gaming and music helped make 50 Cent: Bulletproof one of GameStop's top selling titles in the month of December," said Bob McKenzie, Sr. Vice President of Merchandising.

One of the keys to the title's success may well be the extra content included with the game, making it a must have for fans, despite the actual game being a below average action title. More than four CDs worth of music is included with the game, including new exclusive tracks from 50 Cent, and more than a dozen music videos.

"Gamers and 50 fans alike have enthusiastically responded to the groundbreaking fusion of frenetic gameplay and the lyrical imagery of the exclusive 50 Cent music tracks in 50 Cent: Bulletproof," said Cindy Cook, Chief Strategy and Marketing Officer, VU Games. "The strong sales of Bulletproof underscore the undeniable appeal of the artist, his music and the engaging interactive experience that this game delivers."
