Tom Clancy's Rainbow Six Siege is an online tactical shooter video game developed by Ubisoft Montreal and published by Ubisoft. It was released worldwide for Microsoft Windows, PlayStation 4, and Xbox One on December 1, 2015; the game was also released for PlayStation 5 and Xbox Series X/S exactly five years later on December 1, 2020. The game puts heavy emphasis on environmental destruction and cooperation between players.
Each player assumes control of an attacker or a defender in different gameplay modes such as rescuing a hostage, defusing a bomb, and taking control of an objective within a room. The title has no campaign but features a series of short, offline missions called, "situations" that can be played solo. These missions have a loose narrative, focusing on recruits going through training to prepare them for future encounters with the "White Masks", a terrorist group that threatens the safety of the world.
Siege is an entry in the Rainbow Six series and the successor to Tom Clancy's Rainbow 6: Patriots, a tactical shooter that had a larger focus on narrative. After Patriots was eventually cancelled due to its technical shortcomings, Ubisoft decided to reboot the franchise. The team evaluated the core of the Rainbow Six franchise and believed that letting players impersonate the top counter-terrorist operatives around the world suited the game most. To create authentic siege situations, the team consulted actual counter-terrorism units and looked at real-life examples of sieges such as the 1980 Iranian Embassy siege. Powered by AnvilNext 2.0, the game also utilizes Ubisoft's RealBlast technology to create destructible environments.
Tom Clancy's Rainbow Six Siege is a first-person shooter game, in which players utilize many different operators from the Rainbow team. Different operators have different nationalities, weapons, and gadgets. The game features an asymmetrical structure whereby the teams are not always balanced in their choices of abilities.
The base Counter-Terrorism Units (CTUs) available for play are the:
When the round begins in an online match, the attackers choose one of several spawn points from which to launch their attack while defenders do the same from which to defend from. A one-minute preparatory period will then commence wherein the attackers are then given control over mecanum-wheeled drones to scout the map in search of enemy operators, traps and defensive set-ups in addition to the target objective(s), while the defenders establish their defences and are encouraged to do so without having the defensive and target objective(s) details being discovered, chiefly through destroying the drones. Maps in the game are designed to encourage close quarters combat, and players cannot respawn until the end of a round.

The game features a heavy emphasis on environmental destruction using a procedural destruction system. Players can break structures by planting explosives on them, or shoot walls to make bullet holes. Players may gain tactical advantages through environmental destruction, and the system aims at encouraging players to utilize creativity and strategy. A bullet-penetration system is featured, in which bullets that pass through structures deal less damage to enemies. In addition to destruction, players on the defending team can also set up a limited number of heavy-duty fortifications on walls and deployable shields around them for protection; these can be destroyed through breaching devices, explosives, or by utilizing operator specific gadgets in the case of the former. In order to stop attackers' advance, defenders can place traps like barbed-wire and explosive laser wire traps around the maps. Vertical space is a key gameplay element in the game's maps: players can destroy ceilings and floors using breach charges and can ambush enemies by rappelling through windows. Powerful weapons like grenades and breach charges are valuable, as only a limited amount can be used in a round.
At launch, the game featured 11 maps and 5 different gameplay modes spanning both PVE and PVP. With the downloadable content (DLC) released post-launch with an additional four maps from year one and three maps from year two – there are currently 20 playable maps.
