Parasite is a social deduction Tabletop RPG (TTRPG) set in a cyberpunk dystopia.  
Players take the role of Contracted Associates (CAs) for Interloper Inc, a spaceship R&D company. After being sent on a mission to explore Jupiter’s moon Europa, an alien threat known as the Shifter begins impersonating and
killing off the crew.
The crew is isolated in deep space and too far away from civilization. They figure out which of them is the Shifter before it infests and destroys the ship.
Parasite is a game of my creation. It has 6 different races, 7 different classes, many unique items and weapons, and a whole beastiary of different Shifter forms to play or fight.
All documentation regarding the game for both players and gamemasters is available below for free.
