Team Meat isn't big on having players making tiny payments to unlock stuff for a game they already bought. For the Xbox LIVE version of Super Meat Boy, they're exploiting a feature to provide new content for free through a mode called 'Teh Internets'.
Chapters in 'Teh Internets' will provide 20 levels that either allow any character to go through them or lock one single character to survive through it. One chapter will be available at launch with a couple more to follow; Team Meat will support the feature as long as possible with official and community-made levels done with the PC / Mac editor.
Most surprising of all is Microsoft approving of Team Meat's use of the loophole. Team Meat offers some insight on the matter:
Q: Has Microsoft expressed an opinion on you apparently sidestepping their rules/regulations on how to introduce new content?
A: We were worried about this but, no. we slipped through a loop hole of awesome. In the end they actually welcomed it because they want developers to do anything and everything with their service that makes them stand out. No one has ever done anything like this in the history of XBLA as far as we (and our people at MS) know and it’s seriously the most awesome use of it ever.
360 owners get first crack at the game on October 20 while PC, Mac, and Wii owners can buy it November 2010.
