Possessor

Possessor turns a Minecraft server into a psychological game. One player becomes the Possessor, who can slip into another player's skin and absorb their essence, while the others must survive and work out who is hiding among them. Roles are assigned at the start, and the screen fades when a hunt begins, so the truth about who is who is only revealed later. The goal for the crew is simple to state and hard to reach: survive, and identify the threat before it is too late.

The game revolves around a cat and mouse dynamic. Players explore the map and complete optional tasks, which keeps them moving and gives them reasons to be seen in different places. A brief tactical window lets the Possessor select prey and strike at the right time. When a body is found, suspicion peaks and players gather for a council vote, where each player casts a vote on who they suspect. Possessor is built for 4 to 12 players, and it requires logic, observation and teamwork to deduce who is among them.
