Long talked about but remained in mystery, Harmonix announced they’d be working on a title for XBLA. On X-Play, they finally revealed what they’re working for on our downloadable marketplace and it’s a Rock Band game but not exactly what you think. Rock Band Blitz is a fast, frenetic version that almost resembles Harmonix younger days in rhythm games similar to Amplitude. The best part about it is all the songs you’ve downloaded for the previous Rock Band games work within the new title, regardless of from the first or third game, and also coming with an additional 25 songs in the game. It’s due out this summer and will be shown at PAX East this year and you better believe XBLA Fans will be getting down with the sickness.
