Sky Shield

Defend six prairie towns from incoming warheads. Launch interceptors, trigger expanding blast fields, and use chain reactions to clear the sky before your cities are hit.

Mouse/touch: aim and fire · Keyboard: arrows/WASD + Space · Controller: stick/D-pad + mapped Fire button

Destroy incoming missiles inside your blast fields. Surviving cities and unused ammunition earn end-of-wave bonuses.

Start with 3 command lives. If every city is destroyed, one command life restores the defence line. Earn an extra life every 25,000 points.
