"Def Jam Icon" is an Xbox 360 fighting game starring various hip hop artists. The game is the third in the series and uses a more up-close fighting system then the wrestling-oriented previous titles. The environment and even the music now play a role in fights, and more damage can be done by timing your attacks to the beat of the background songs. Like all other Xbox 360 games, this one features "achievements" and accomplishing these will also reward the player with chains and clothes to customise their character.
