About this game

Defend your base from an endless onslaught of atoms in this fast-paced, chemistry-themed shooter. Master the periodic table, exploit atomic bonds, and unleash 14 unique weapons.

⚛ ATOMIC ASSAULT
Fire projectiles to destroy incoming elements before they breach your defenses. Each element has unique behavior and vulnerabilities.

🔗 COMPOUND BONDING
Atoms bond together to form powerful compounds with devastating effects. Strategically let them bond — or blast them apart before chaos erupts.

📈 ENDLESS WAVES
Progress through waves of increasingly aggressive elements. The further you go, the more dangerous and exotic the chemistry becomes.

🎯 STRATEGIC TIMING
Master when to fire and when to wait. Exploit compound reactions, trigger chain explosions, and turn enemy chemistry against them.

The further you push, the more complex the chemistry. Adapt your strategy, upgrade your weapons, and never stop learning the elements.

Protect. React. Survive. How long can you hold the line?
