You'd think one April Xbox Live schedule would be enough, but apparently not for Microsoft. The company just issued another release schedule packed with Xbox Live Arcade, DLC, Games on Demand, Avatar goodies and Deals of the Qeek. Leading the pack is the long-awaited release of Tecmo Bowl Throwback. Xbox owners can also expect new Game Room titles, Left 4 Dead 2 and BioShock 2 DLC and a half-priced The Dishwasher: Dead Samurai. Check out a full list of the impending releases after the break.
