Nano War is back, featuring a single player campaign with upgrades, and a multiplayer mode. Your goal in Nano War 2 is to eradicate the enemy by transferring units from one cell to another. A cell that is controlled by you is blue and a cell that is controlled by your opponent is red. The larger a cell is, the faster it will produce units. Upon completing a level, you will receive points, which will allow you to upgrade your cells.
