Events Among Us takes place on the first map The Skeld - the very and main map of the game, which is a spaceship.

The game, inspired by the salon role-playing game "Mafia", is made in a sci-fi theme; the players in it are randomly divided into two teams: the crew members and the traitors hidden among them. The crew members do not know which of their comrades is the traitor, and can vote "execute" any character, trying to identify the traitors through deduction. Crew members win if they manage to get rid of the traitors or at least complete all the puzzle missions offered to the crew; traitors win if they manage to secretly kill enough crew members without getting caught or bring a major sabotage to completion - for example, blow up a reactor.
