Aliens are invading. You are the head of a team which chooses where to strategically place bombs to destroy their ships. You must protect the ancient monument, The Temple of Gold. Drag bombs from the bottom left corner to hit the aliens. Black bomb- free, two seconds to explode. Green bomb- costs 50$, two seconds to explode, larger explosion. Blue bomb- costs 50$, one second to explode. You earn 10$ and 1000 points for each alien ship you destroy.
