Spare Parts is coming out this week on XBLA and PSN for $9.99 (800 Microsoft Points). In this online co-op platformer, two robots are stranded on an alien planet, forced to collect junk to repair their ship and go back home. With its cartoony style and its focus on wacky alien technology, it's reminiscent of the Ratchet & Clank franchise.
As explained in this dev diary (after the break), you'll need a friend to discover all the secrets and unlock all the Achievements in Spare Parts. You'll also get access a number of special tag-team bonuses, like a synchronized high-five that refills your health. If you aren't entirely sold on the concept, a co-op enabled demo will also be available this week.
