CrystalReactor vs SoulStack

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.

SOULSTACK — a necromancer auto-battler of stacked souls. You were a master of death, stripped of power and cast into the Pit: an endless tower of the dead. But every foe you slay rises to serve you. Recruit them. Fuse them. Weave a legion that multiplies — and climb. ◆ A LEGION THAT COMPOUNDS Draft undead, beasts, mages, and rogues into your warband. The power isn't flat stats — it's synergy. Line up the right tribes, roles, and Authorities and your army doesn't add up, it MULTIPLIES. Find the engine, break the wall. ◆ CLIMB THE ENDLESS PIT Every run is a fresh draft. Scout the floor ahead, counter it, and climb — the dead grow without limit as you rise. Fall, and you return to Level 1… but the servants you raised carry into the next life. Rise again. ◆ COMPETE WITH FRIENDS — ON YOUR TIME Conquer the Pit and set your army to guard your star. Then raid your friends' stars across a season of standings. It's all ASYNC — no live matches, no waiting, no always-online. Take a turn whenever you like; the war continues without you. ◆ FAIR BY DESIGN Premium — buy once. No ads. No gacha. No pay-to-win: the unlock sells the full climb and the collection, never power. Competition is normalized, so skill wins, not spending. ◆ THEORYCRAFT-DEEP Deterministic combat and simulation-tuned balance reward mastery over luck. Dozens of units, items, and Authorities to combine — the deeper you read the synergies, the higher you climb. Raise the dead. Stack the souls. Climb.
