Harmonix's Rock Band Blitz for Xbox Live Arcade and PSN was announced last night, but now the studio is sharing a trailer and some more details on the game. Featuring gameplay similar to that of Rock Band Unplugged (or HMX's Amplitude or Frequency), the game has you sailing down a note highway, tapping blocks and switching instrument tracks for maximum points. There are several control layouts available, allowing you to switch instruments using bumpers and hitting blocks using buttons or analog sticks.

Rock Band Blitz will launch with 25 tracks, including "Pumped Up Kicks" by Foster the People, "Jessie's Girl" by Rick Springfield, "Always" by Blink-182 and "Bang your Head" by Quiet Riot. All 25 tracks will be available to play in Rock Band 3. The game will also have access to the full Rock Band Music Store.

However, you will not be able to export the disc-based Rock Band 3 tracks into Rock Band Blitz, since they don't reside on the hard drive. Asked whether Harmonix was working on an update to allow import of disc tracks as an option, a representative told us, "We don't have plans at this time."

Blitz will be out this summer.
