Citadel InterceptSkyline Defense

Defend the six cities

Launch counter-missiles from the nearest operational battery. Each counter-missile detonates at the reticle, creating an expanding blast that destroys enemy warheads inside it.

Think in chain reactions

One well-timed blast can trigger several enemy missiles at once. Shooting high in the sky protects more territory and gives the blast time to expand.

Know the threats

• ICBMs descend in straight attack lines.
• MIRVs split into multiple warheads if they reach the lower sky.
• Smart missiles weave and try to skirt active blast zones.
• Bombers appear in later waves and release additional weapons.

Manage ammunition

Each battery has limited missiles. A cyan supply craft may cross the upper sky; tap it directly to refill every operational battery. Remaining ammunition and surviving cities are converted into end-of-wave points.
