50 Cent: Bulletproof G Unit Edition was developed by High Voltage Software and published by Vivendi Games for the PSP on August 29th, 2009.
Despite its title, G Unit Edition is a distinctly different game from 50 Cent: Bulletproof. While the game does retain the same story and cut-scenes as the console counterpart the game eschews a behind-the-back perspective for isometric shooting ala Killzone: Liberation. Mulitplayer gameplay was also added to the game through ad hoc wireless connectivity. The game also featured a "Vitamin Water" mini-game in which you play as 50-Cent at the apex of his business endeavors. Because of this, it was slightly better received than the console versions.
