Steal bodies. Survive the dungeon.

Parasite Survivor is a possession-based roguelite RPG where you become a mysterious parasite slime and survive by taking over the bodies of monsters.

The story takes place in the Graveyard, a vast dungeon region in the western part of the godless world of Royarna.
Fight monsters, weaken them, possess their bodies, and move from one form to another as you struggle to survive.

Cute monster girls, powerful boss-class monsters, terrifying undead, and adult event scenes unlocked through possession await you.
Battle, steal, switch bodies, and build your own twisted parasite lineage.

Main Systems

• Body takeover through parasitism
  Weaken enemies and successfully possess them to use their bodies. Stronger bodies allow you to challenge even more dangerous foes.
  
  
• Day-by-day survival
