Swarm, their Lemmings-like action game, will be coming to PlayStation Network on March 22, and Xbox Live Arcade on March 23: It's 3/22 PSN, 3/23 XBLA. Kept it short and simple to fit in 140 chars. :)
Swarm lets the player take control of 50 utterly fearless Swarmites and drive them through an intense, entertaining and often suicidal battle for a greater good. Run, bash, huddle, boost, stack, jump, push and throw your way through gauntlets of death and destruction in an attempt to collect valuable DNA and ensure that at least one Swarmite survives.
Having checked it out this weekend at PAX East 2011, it seems like a great addition to the digital download services. The trailer was even better.
