Gameplay

Impostor is a multiplayer game for four to ten players. One to Two players (depending on what the host selected) are randomly chosen to be the impostor(s) each round. A game can take place on one of four maps: Station, Containment, Vulcan and Crystal Tundra (NEW)At the start of the game, Innocents are given "tasks" to complete around the map in the form of minigames, consisting of maintenance work on vital systems such as replacing fuses and checking servers. Impostors are given a fake list of tasks to blend in with Innocent s, although they are unable to actually complete any task. Impostors can sabotage vital systems, covertly travel through air vents, and work with other Impostors to kill Innocent s. If a player dies, they become a Ghost.

The Innocents win by completing all tasks, or by identifying and eliminating all Impostors. The Impostors win when the number of Impostors is equal to the number of Innocents, or when a sabotage countdown reaches zero. When an Impostor performs a sabotage, either there is an immediate consequence (such as all the lights being turned off) or a countdown begins. In the latter case, if the sabotage is not resolved before the countdown finishes, the Impostors win. Sabotages can be resolved by living players in varying ways depending on which sabotage is performed. Games can also end by players quitting the match if doing so fulfills any win condition; a player quitting is equivalent to them being eliminated, and a Innocents quitting leads to their tasks being considered completed for the total.

To help the Innocents identify Impostors, there are various surveillance systems in each map, such as a security camera system on Station, Containment,Vulcan and Crystal Tundra (NEW). Any living player may call a group meeting by reporting a dead body, or by pressing a button in the map at any time. This halts all other gameplay. In the meeting, players discuss who they believe is an Impostor based on the available evidence. A plurality vote is held, and the chosen player is voted off and dies. Players can communicate in a chat, but only during meetings, and only if they are alive (though ghosts can speak with one another at any time). While the game does not have a built-in voice chat system, it is common for players to use external programs such as Discord while playing.
