So earlier today, a tweet from Platinum Games teased that a launch trailer for Teenage Mutant Ninja Turtles: Mutants in Manhattan (based on the IDW ongoing series and not any of the cartoons, or live-action movies. Though we do get a tease of one character who was from the Archie Comics and someone who just debuted on the Nick Cartoon) was coming Tuesday. But given that this game has had leak after leak, of course the launch trailer has leaked too. Well, someone on X-Box.com got a bit too launch happy and that's how this trailer is out (also why the X-Box label is the first thing seen - don't worry this is gonna be a multi-platform game).
Here it is (when a better higher-res version is posted I'll update it):
As for when the game come's out, it's sometime this summer. More than likely we'll get some more official release information tomorrow.
