Click on the empty tiles to the left to construct buildings, use them to defend your base from enemy and to produce units to attack them. All structures are upgradeable, which makes either them or units they produce more powerful.
Droids are threatening world domination and there are only a few humans left to stand up to them! Defend key territories from an onslaught of merciless droids as you struggle to protect the precious resources you have left.
Your goal in this defense game based on StarCraft is to play as the Zerg Overmind and build up your defense and survive the combined Terran and Protoss attacks.
