According to the official Team Meat Twitter, Xbox 360 owners who purchased the meat-tastic title can expect a DLC pack (according to Joystiq, it'll be free) consisting of expert remixed levels and user created levels, which is pretty awesome.
We're big fans of Super Meat Boy and of the Team Meat guys, so show some support for the game if you haven't already.
