Build. Merge. Survive the Chaos.

GreySpire is a tower defense adventure where strategy meets unpredictability. Towers are random, enemies are relentless, and survival depends on adapting to the madness. Merge your defenses into stronger forms, unleash wild abilities, and face endless waves of escalating chaos.

Chaotic Tower Defense

Every tower you summon is a surprise. Poison, teleport, fire, spinning blades — you never know what the battlefield will give you. But through merging, identical towers evolve into devastating higher tiers with boosted stats and game-changing powers. Each run is a new test of adaptation, luck, and explosive synergy.

Relentless Enemy Waves

The enemy grows stronger with every wave. Their health increases relentlessly, testing your towers’ strength and forcing you to evolve your defenses through merging, upgrades, and abilities. Each new wave is a battle of endurance as you push back against the ever-mounting pressure.

Farm, Fish, and Forge

Gold is everything. Grow wheat across waves to build steady income, risk it all fishing for a chance at massive rewards, or craft weapons at the blacksmith to permanently boost tower damage, range, and speed. These side paths turn downtime into opportunity, fueling your defenses with vital resources.

Progression That Lasts

Every run pushes you further. Earn experience, level up, and unlock powerful bonuses that stay with you across games — from more starting gold and tower discounts to richer harvests and better fishing hauls. Each defeat makes you stronger, every run more explosive, until the chaos finally bends to your will.
