Nucleon

Nucleon is a thrilling HTML5 arcade experience where you become a scientist splitting atoms and unleashing true neon chaos. The game brilliantly blends platforming, shooting, and puzzle mechanics: fire your laser beam at atoms like Kr, Ar, Ne, He, and H, breaking them into smaller particles. But beware of U-235! The core mechanic is based on fission: large atoms (such as krypton) split into two smaller ones (argon), while unstable atoms from level 4 onward split into four at once. You’ll face 20 levels with steadily increasing difficulty: timers speed up atoms, sudden gusts of wind alter trajectories, platforms block beams and particles, and a lever lets you lock barriers into position. Every 3–8 seconds, boosters drop as isotope canisters: Time Stretch, Triple Beam, Jetpack, Evaporation, plus 5 more bonuses — 9 power-ups total for smart tactical play. Two modes, full two-player co-op, and smooth touch controls for mobile devices.
