The game will allow you to connect your iPad to lots of other devices, like the iPhone, iPod touch, Mac, PC or Android, and play CO-OP with a friend, using local Wi-Fi.
The iPhone and iPod touch version comes as a free game update and it is now waiting for approval. The Mac, PC and Android versions will be ready in January 2011.
Using your iPad, you’ll also be able to play with a friend in Split Screen mode, on the same device.
