Alien Chain Reaction Puzzle

ALIEN CHAIN REACTION - a pixel-art arcade puzzle built on explosion physics. One tap. One rocket. A whole alien fleet gone. Tap the screen to launch a rocket. The blast damages every UFO nearby - and damaged ships go critical and detonate on their own, tearing apart their neighbours. A single well-aimed shot can sweep the entire screen in one long chain reaction. HOW IT PLAYS Aim, tap, and let the physics do the rest. Every explosion pushes, damages and destroys. Learn the blast radius, read the drift of the alien formation, and find the one spot where the whole fleet collapses at once. Easy to pick up in five seconds, hard to master. 40 CAMPAIGN LEVELS Hand-tuned levels that start gentle and turn into real brain teasers. Limited rockets - every shot has to count. Earn up to three stars per level, and switch to Hard when normal stops hurting. THE ALIEN FLEET Basic scouts pop from a single hit. Heavies soak damage. Shielded ships need two. Splitters break into smaller UFOs when destroyed - and those detonate too, if you set them up right. ENDLESS SURVIVAL Waves of UFOs keep coming and never stop. How long can you hold out, and how big a chain can you build before you run out of rockets? DAILY CHALLENGE One fixed layout per day, identical for every player in the world - same formation, same drift, same power-ups. Pure skill, no luck. Come back tomorrow for a new one. POWER-UPS Shoot the bonuses that drop out of destroyed UFOs: extra rockets and a bigger blast radius that turns a good shot into a screen-clearing one.
