One music game that slipped out of this fall was Def Jam Rapstar. The hip-hop focused game looks to cover a genre of music that is generally not well represented in today's rythym and music titles.
The game will offer a few modes of cooperative play, including pass the mic, and after watching the latest two trailers - I hope there's a bit of a free style mode. The game is currently scheduled to be released sometime next year on the Xbox 360 and PlayStation 3, though no specific window was given.
The official website was just launched where you can check out a few more details as well as the normal Twitter/Facebook/social media gathering.
For now enjoy the new screens and trailers.
