Ghost Recon: Future soldier seems to be making use of Kinect in quite an interesting and more hardcore way than we have seen before.
Optimise, and test your weapon with this Gunsmith feature.
This is also controller compatible, however, I think this could dilute some of the appeal to play Ghost Recon with the Kinect. People like controllers (or mice and keyboards) when it comes to first person shooters, given the choice I feel people would sway towards the existing technology. I’m not sure that this will sit right with the community and will end up being a gimmick rather than a valuable tool.
