Among Us is a multiplayer social deduction game developed by InnerSloth. In the game, players are randomly assigned the role of Crewmates or Impostors aboard a spaceship. The Crewmates are tasked with completing various tasks around the spaceship while the Impostors are trying to sabotage the mission and kill the Crewmates without being caught. The game is won either by the Crewmates completing all their tasks or by the Impostors successfully eliminating all the Crewmates.

During the game, players can call meetings to discuss any suspicions they may have about the identity of the Impostors. The Crewmates can vote on who they think is the Impostor, and the player with the most votes is ejected from the spaceship. This player may be either an Impostor or an innocent Crewmate.

The game features various maps, each with unique locations and tasks for the Crewmates to complete. There are also different customization options available for players, including hats, skins, and pets, which can be purchased using in-game currency.

The game has gained popularity due to its unique gameplay mechanics and the ability to play with friends and strangers online. It has become a cultural phenomenon and has even inspired a popular meme.
