Tom Clancy's Rainbow Six: Siege is a multiplayer tactical first-person shooter centered on counter-terrorist operations. Rather than focusing on a single-player campaign, the game emphasizes team-based competitive and cooperative scenarios where players assume the roles of specialized operators drawn from international counter-terrorism units.

The core gameplay is structured around asymmetrical matches that pit attackers against defenders. Attackers attempt to breach fortified positions using explosives, drones, and specialized equipment, while defenders prepare barricades, deploy traps, and use surveillance systems to hold their ground. Environmental destruction plays a central role: walls, floors, ceilings, and barricades can be breached or reinforced, creating new sightlines and tactical options during every match.
