Race toward stability

ZERO//DECAY is a frantic roguelite action-platformer where you play as an unstable nucleus. Dash through bullet hell, collect epic mutations, build wild synergies — or die fast and try again.

• Dash. Dodge. Decay.

Movement is survival. Jump and dash through readable chaos, keep your combo alive, and never stop moving.

Mutate or fall apart

Every run reshapes how you fight. Stack melee, ranged, dash, and jump mutations — then chase synergies that turn a fragile nucleus into something dangerous.

Features

• Fast, tight 2D action-platforming in dense bullet-hell arenas
