Back in June, Def Jam released the official trailer to the karaoke-style rap game RAPSTAR. The game features official tracks from Def Jam artists but according to gaming site Kotaku, that’s not all. A big part of the game will be the online feature where gamers can freestyle to various provided beats and record video of their own songs as well.

The freestyle tracks will even have the ability to add layers giving gamers the opportunity to add background vocals and other layered instruments on top of their beats. Seems like a pretty cool feature as long as the gaming community will actually take part in it and record their own tracks. Expect Def Jam Rapstar to hit officially this “Winter,” which likely means sometime in Q1 2010.
