Alien Chain Reaction

ALIEN CHAIN REACTION — a pixel-art arcade puzzle built around explosion physics.

Tap the screen, launch a rocket, blow up a UFO — and its blast tears apart its neighbors. Trigger a chain reaction of dozens of annihilations with a single shot.

🚀 ONE TAP, ONE CHAIN REACTION
Every explosion damages nearby UFOs. Heavily damaged ones turn "critical" and self-detonate a second later, igniting the next link. Wipe them all out before your rockets run out.
