Overview

Science Monster: Grafted Heart is a unique organ-building survival roguelite developed and published by JIELIN. Instead of traditional classes or weapons, players graft living organs into a mutating body to survive. Each organ possesses distinct characteristics, including shape, weight, blood demand, heat output, and unique attack behaviors, contributing to a dynamic combat system.

Highlights

  • Organ Grafting System: Players build their combat capabilities by grafting various living weapons and support organs into a mutating body, rather than selecting classes or equipping traditional gear.
  • Dynamic Combat: Organs like bone cannons, frost glands, acid glands, and parasite wombs offer diverse offensive and defensive capabilities, with support organs and mutations further altering combat effectiveness.
  • Roguelite Survival: The core gameplay loop involves moving, surviving, and collecting temporary catalysts to empower equipped organs, creating unique builds in each run.

Who It's For

This game is for players who enjoy roguelite experiences with a strong emphasis on strategic build-crafting and emergent gameplay. Fans of top-down shooters and bullet hell games looking for a fresh take on combat mechanics will find the organ-grafting system particularly appealing.
