The goal of this game is to blow up all the atoms that are flying around in the space. That's not a war, but a great fun!
There are go game modes: strategy and time based. In strategy mode you can shoot the atom whenever you want, and in time based game - the atom will be automatically released after some period of time. Also you can change the gravity and the rotation speed.
