Parasite is a first-person multiplayer social deduction game set in a mysterious mansion with a retro, "PlayStation-inspired aesthetic".
Among the witnesses hides a parasite determined to eliminate them. Watch how others behave, share your suspicions, and decide who to trust. A familiar face is no guarantee of safety: the creature can hide inside another player, waiting for the right moment to take control.
As a Witness, explore the mansion and collect parts to craft improvised weapons and detection equipment. Stay close to your companions, investigate suspicious behavior, and help the group survive.
The Detective carries a weapon and must decide when to act. Listen to the other players and choose your target carefully—a convincing accusation does not always point to the real threat.
The Researcher has a detector and extractor to investigate possible infections and force the parasite out of its host. Testing takes time, and the results can be misleading. Work with the others to uncover the creature and protect each other during an extraction.
Playing as the Parasite? Enter another player's body and remain hidden inside while they continue moving around, unaware of your presence. Take control of your host to turn suspicion against them, deceive their companions, or strike when the group is vulnerable. Choose when to stay quiet and when to reveal yourself.
Explore the mansion, plunge its corridors into darkness, and keep an eye on your companions. Danger might be standing right beside you—or hiding inside you.
