About This Game

Science Monster: Grafted Heart is an organ-building survival roguelite. You do not pick a class or equip a weapon. You graft living weapons and support organs into a mutating body.

Every organ has its own shape, weight, blood demand, heat output, and attack behavior. Bone cannons fire rapid spikes, frost glands slow and freeze enemies, acid glands leave corrosive pools, and parasite wombs release hungry larvae. Support organs, tissue zones, and mutations further change how your body fights.

In combat, your body attacks automatically. Your job is to move, survive, and collect temporary catalysts. Catalysts briefly empower organs you have already equipped, turning each build into a different combat rhythm. Stack bone firepower, freeze crowds, melt armor with acid, spread parasites, or carve through enemies with orbiting blades.

Enemies close in from every direction. Elites and bosses use warning attacks that force you to read the battlefield, reposition, and trigger Adrenal Burst at the right moment. When you fail, rebuild your body, change your organ layout, and try again.

The game includes Stage Challenge and Endless Challenge modes. In Stage Challenge, you unlock higher difficulties, new organs, and deadlier enemies. In Endless Challenge, you begin with a basic body and see how far your build can survive against an escalating horde.

Key Features:

- Freely graft organs onto a living body

- Balance blood supply, heat, weight, and tissue zones

- Multiple weapon archetypes and combo effects

- Collect temporary catalysts during combat to change your power curve

- Dodge elite and boss warning attacks through positioning

- Rebuild after failure and try a different survival plan

- Stage Challenge and Endless Challenge modes
