Tom Clancy's Rainbow Six Siege

Tom Clancy's Rainbow Six Siege is a 2015 tactical shooter game developed by Ubisoft Montreal and published by Ubisoft. 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, or taking control of an objective within a room. The title has no campaign but features offline training modes that can be played solo. 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, which inspired the map Consulate. Powered by AnvilNext 2.0, the game also utilizes Ubisoft's RealBlast technology to create destructible environments. It was released for PlayStation 4, Windows, and Xbox One in December 2015, PlayStation 5 and Xbox Series X/S in December 2020, and Google Stadia in June 2021. The game received an overall positive reception from critics, with praise mostly directed to the game's tense multiplayer and focus on tactics. However, the game was criticized for its progression system and its lack of content. Initial sales were weak, but the game's player base increased significantly as Ubisoft adopted a "games as a service" model for the game and subsequently released several packages of free downloadable content.
