About

CrystalReactor

Read full description

Crystal Reactor is a neon sci-fi arena defense game where you protect a living crystal core at the center of the battlefield. Waves of machines rush in from every side while your reactor fights automatically — you focus on strategy, upgrades, and survival. After each wave, choose one of three technologies to strengthen your build. Stack lasers, chain lightning, plasma, freeze effects, shields, and orbital drones. Combine compatible powers to unlock fusion upgrades like Cryolaser, Ion Storm, and Thermonuclear Charge for devastating new attack patterns. Pick from five reactor cores, each with its own technology tree and playstyle. Laser favors precise beams, Electric chains lightning across crowds, Plasma delivers heavy explosions, Gravity pulls enemies inward, and Cryo slows the arena under your control. Fight across six unique zones with their own rules. Slippery ice speeds up attackers, low gravity on the space station extends your range, biolab swarms regenerate, desert heat weakens shields, underground corridors bring denser spawns, and volcanic vents damage everyone on the field. Between runs, spend crystals and technology cores in the Meta Lab. Unlock new reactors, open additional zones, expand your technology slots, and buy starting bonuses. Every run teaches you a new build — every victory pushes your core further. Features: • Automatic arena combat with wave-based enemy assaults • Roguelike technology drafts and fusion combinations • Five reactor types with distinct upgrade paths • Six arenas with unique hazards and enemy behavior • Boss fights including Titan, Carrier, Omega Core, and Void Crystal • Permanent meta progression between runs • Neon sci-fi visuals optimized for iPhone and iPad Defend the core. Forge the perfect reactor. Survive the next wave.
