Microsoft has bundled another four Xbox Live Arcade games to offer them on the cheap. The new "Action Packed Bundle" includes The Dishwasher: Vampire Smile, Dungeon Fighter Live, Islands of Wakfu, and Unbound Saga.
The bundle is available on the Marketplace for $20 altogether. Sold individually, the games would cost $45 total. If you already own one of the games, though, you don't get a discount or additional copy of the game. Still, if you want any of two of those four games, it's like getting the others for free.
