Crossout is a free to play MMO that focuses around PvP engagements, with some PvE elements. Gameplay revolves around the creation and upgrade of the gamer's vehicle through combat. There are no defined classes, all vehicles are built by the player whoever they like. This allows for gamers to choose exactly what weapons and what weight class they want a vehicle to be. If they want a fast effective glass cannon, they can make it. If they want a heavy duty tank, they can create that as well. It has an advanced physics engine which will accommodate different player builds. A heavy vehicle will be less manoeuvrable, for example.
