Monster Gacha: Parasite Survivor

Parasite Survivor is a roguelike RPG where you play as a parasitic slime capable of possessing monster bodies to survive a dangerous dungeon. In the graveyard called Graveyard, you must outlast a set number of days by defeating monsters, weakening them, and then taking over their bodies through parasitic possession. Each body has different stats and abilities—from goblins to ghuls to demon-class fighters—and you must strategically switch between hosts to handle increasingly difficult encounters. The game features a 'monster gacha' element with multiple monster girls and bosses to possess, a possession-history system to track your lineage of bodies, upgrades purchased with parasite points, and multiple endings. All encountered monsters can be possessed, and the game includes intimate recall scenes unlocked through successful parasitic takeover.
