To Protect the Earth from alien invasion, you're given a ship class AT-021. But unfortunately the Earth doesn't have enough resources to supply new arms to the ship. Improve the ship by collecting weapons through battles and buy turrets to defend.
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.
Defend your base! Use your magnetic ship to pick up chunks of junk and drop them on advancing enemies. Absorb junk into your ship and base to upgrade them and assure your victory.
Defend the castle from the attack of orcs and other creatures. Get gold in order to create soldiers and archers, you will also be able to repair and upgrade units.
Build towers and survive through 51 hardcore waves of aliens that heal themselves, haste other enemies, split into more enemies and freeze your towers.
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.
