A massive online multi-player war strategy game.
Its game play is split into two completely different worlds, the past world versus the future world. And as a player in the game you get to be in one of the worlds, and play against other players in the opposite world!
In both worlds you get to summon and train warriors to fight for you and defend your bases. Both worlds warriors attack in completely different ways, yet both are relatively equivalent in strength, and the strategy used is what makes the difference!
