Tom Clancy’s Rainbow Six Siege, developed and published by Ubisoft, is a highly competitive tactical first-person shooter that emphasizes strategy, teamwork and environmental destruction over traditional run-and-gun action. Each match pits two teams of five—Attackers and Defenders—against each other in objective-based scenarios such as Bomb, Secure Area and Hostage.
 

A defining feature of Siege is its destructible environments. Walls, floors, ceilings, barricades and hatches can be breached or reinforced, allowing players to create new sightlines, entry points and defensive setups. This system ensures no two matches play out the same way.
 

Players choose from a diverse roster of Operators, each equipped with unique gadgets, weapons and abilities. Attackers specialize in breaching, intel gathering, and area control, while Defenders focus on fortification, traps and denial tactics. Operator synergy, map knowledge and communication are essential for success.
 

Gameplay is intentionally lethal—low time-to-kill means positioning, sound cues and decision-making matter more than raw aim. Matches are tense and methodical, rewarding patience and coordination. Siege offers multiple modes, including Casual, Unranked, Ranked, Custom Games and limited-time events.
 

Rainbow Six Siege has evolved significantly since launch through continuous updates, seasonal content, reworks, balance changes and new operators and maps. It boasts a thriving esports scene, with international tournaments and a dedicated competitive community.
 

With its deep tactical depth, high skill ceiling, and ever-evolving content, Rainbow Six Siege remains one of the most influential and enduring multiplayer shooters in modern gaming.
