The latest Xbox Live Newsbeat update included release dates for two pieces of downloadable content that we didn't even know existed. We typically don't care for surprises, but we're willing to make an exception if it means we get more maps for the multiplayer component of BioShock 2 and more things to explode in Just Cause 2.

On April 29, six new multiplayer maps will be added to BioShock 2 as part of the "Rapture Metro Map Pack." For 800 ($10), players get the new arenas, three new masks, a "Kill 'Em Kindly" Melee deathmatch mode, and three new Achievements. Just Cause 2 will receive the "Black Market Aerial Pack," a 160 ($2) booster which adds the chaingun-toting F-33 DragonFly Jet Fighter, a multi-lock missile launcher and a parachute thruster which extends your airtime whilst leisurely sailing across the Panauan landscape. How... unexpextedly soothing!
