We just recently found out that The Adventures of Tintin: The Game has a two person local co-op mode. The movie tie-in is a platformer with some other genres mixed in for good measure. We have a new video today where you can see some of the gameplay elements as well as the co-op mode in action. It looks kind of interesting and there seem to be multiple puzzle elements. You can even play as Tintin's dog, Snowy (Or Milou, si vous parlez français.)
The Adventures of Tintin: The Game is out now on the Xbox 360, PlayStation 3, PC, Nintendo Wii, and 3DS. It supports a two player local co-op mode.
