Crytek's Warface Xbox 360 Edition is now available for free to all Xbox LIVE Gold members through the Xbox Game store. John got his hands on it at way back at E3 2012, and he had a lot of good things to say about it.
Warface has four classes to choose from that are all fairly self-explanitory: The Rifleman, Sniper, Medic and Engineer. Each class comes with unique weapon sets and gameplay styles; but what really caught my eye is the ability to modify your weapons mid-match. You'll be able to play with a constantly-evolving set of maps and content in five-player Co-op mode, as well as a Versus mode that can hold up to sixteen players.
