This is it, guys. When it was revealed that Aliens: Colonial Marines would be a game on the Wii U, this is what you wanted. You wanted an actual Motion Tracker. Well guess what? You got it, as described in this dev interview.
The GamePad will also work as a standard map. We should probably get used that.
The release date for the game on other systems is February 12, 2013, so hopefully that’s a good indicator of when the Wii U version will arrive, too.
