SCP-5555 is an anomalous game taking place in the SCP universe where the players have roles of people that control the world. They are all immortal but can 'die' technically which is the win condition: 'kill' everyone else. You can attempt to make alliances with other players or attempt to eliminate them from the game. They can contact you or you can contact them via a wide variety of methods such as email, physical letter, or meetings. These things can also happen without the user causing it.
