Tom Clancy's Rainbow Six Siege

Tom Clancy's Rainbow Six Siege is Ubisoft Montreal's tactical 5-vs-5 multiplayer shooter, long considered the reference point for the modern team tactical shooter subgenre. Rounds alternate between attack and defense with single-life stakes and a heavy emphasis on intel, coordination, and environmental destruction.

Defenders fortify objective sites with reinforceable walls, barricades, traps, and gadget cameras, then hold them against attackers who use drones for scouting, breaching charges, rappel rope, and operator-specific tools to find openings. Destruction is procedural and granular — walls become windows, floors become breach points, ceilings drop on heads.

Dual Front is the newest mode: 6-vs-6 on the largest map in the game, with teams pushing sectors back and forth and a Neutral Sector offering high-risk side objectives that swing the wider battle.

The operator roster has expanded across the years' worth of seasons, each operator with their own gadget and role. Quick Match, Unranked, and Dual Front are free; Ranked, the Siege Cup, additional operators, and cosmetics require payment. 80+ million registered players, an active esports scene, and seasonal content updates keep the game evolving roughly nine years after launch.
