Ghost Recon: Future Soldier will be better with Kinect when it launches. At E3 this year Ubisoft showed off some of the gunsmith features which utilize Kinect.
The game will have 20 million unique weapons, which can be created using either your voice or gestures. The presenter showed how individual parts of each weapon can be swapped out with his gestures and his voice. He even showed how the weapon can be reassembled and tested on the field.
The short Ghost Recon: Future Soldier gunsmith demo can be seen below.
At the end of the quick demo Ubisoft noted that all future Tom Clancy games will use Kinect in some fashion.
