Missile Defense

Controls Tap the screen and the nearest battery fires an interceptor to that spot, where it explodes. Enemy missiles caught in the blast are destroyed, so lead your shots. An enemy that reaches a city destroys it; you lose when all cities are gone. There are 3 batteries with 8 shots each, refilled after each wave. Each kill is worth 25 × wave (up to ×6), and each surviving city at the end of a wave adds 100. Keyboard: arrow keys to aim, Space/Enter to fire.
