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.
You are a giant armored robot, and you must shoot all that attack you. There are many upgrades and many possible kits to use. Play through all 10 levels.
Play as a machine gunner defending your beach from an enemy invasion. Survive 10 waves and win the game. Each wave gets harder and harder. Don't allow more than 10 enemy soldiers make it to your defensive wall.
Protect your communication tower against the enemy air strike. The earlier you take down enemy planes the more money you will get! You can buy or upgrade weapons for earned money and try to keep your tower safe as long as possible.
