IGN - If you're not familiar with Wargaming.net's free-to-play game World of Tanks, the premise is simple: take a shooter and replace the people with massive, lumbering and highly realistic tanks. Narrow corridors are replaced by wide, open vistas, and your range of weapons are replaced by... more tanks. A whole world of them, actually. The structure of World of Tanks is session-based, like playing a round of Counter-Strike, and like Counter-Strike there are two ways to win each session. Either destroy all of your opponents or capture their base.
