About this game

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.

🎯 MODES
• Campaign — 40 levels of escalating difficulty + Hard mode.
• Endless — survive rising waves and chase the high score.
• Daily Challenge — one shared seed per day. One attempt.

👾 ENEMIES
• Basic — one rocket and gone.
• Heavy — soaks more damage.
• Shielded — two hits required.
• Splitter — splits into two smaller UFOs on death.

🏆 PROGRESSION & LEADERBOARDS
• Star ratings per level — for speed and efficiency.
• 24 achievements for different playstyles.
• Global leaderboard by total best score.
• Separate Weekly / Daily / Endless ladders.

⚡ POWER-UPS
