Tom Clancy's Rainbow Six Siege is a tactical first-person shooter focused on close-quarters combat between teams of five. Players select from a roster of operators drawn from counter-terrorism units around the world, each with unique gadgets and abilities. One team attacks objectives such as defusing bombs or rescuing hostages, while the other team fortifies and defends. The game emphasizes destructible environments, with players able to breach walls, ceilings, and floors to create new lines of sight. There is no respawning within rounds, making each player's survival critical. The title has no single-player campaign but includes training modes and cooperative scenarios against AI opponents.
