Gaijin is known as developer of War Thunder and their upcoming vehicle combat MMO Crossout is going to start a small scale test, available for selected players. Those who are not eligible for this test can sign up at the official site for the chance to join following tests.
Crossout stresses on physics and freedom. You can build your combat vehicle freely with tons of parts, and how you build your vehicle decided how your vehicle fights. The advanced damage physics allows you to destroy opponent vehicle's parts and therefore disable particular functions. Of course you can always completely destroy an enemy vehicle.
