The newest title out of Gameloft is pretty self-explanatory. Tank Battles is about, you guessed it, tank battles. This game invites you to design and control your own custom war machine and fight your way through 80 top-down missions of increasing difficulty. Fighting computers not doing it for you? There's multiplayer too.
Tank Battles doesn't take a photo-realistic approach to the whole military warfare thing – it's a bit wacky and over-the-top.
