AA vs Aliens!

Take command of the air-defense system and protect a radar station from an alien invasion. Your arsenal includes twin cannons, flak burst, guided missiles, a laser cannon, and an atomic charge. Intercept fast targets and hostile projectiles, use thermal vision during night attacks, purchase ammunition between battles, and unlock new equipment as the campaign progresses. Clear 30 waves or enter Endurance mode, where the assault grows stronger over time. Accuracy, reaction speed, intercepted threats, and station integrity all contribute to your final score.
