Rainbow Six Siege

Ubisoft Montreal developed and Ubisoft published Tom Clancy's Rainbow Six Siege, an online tactical shooter video game. It was initially released worldwide on December 1, 2015, for PlayStation 4, Windows, and Xbox One. The game was also launched for PlayStation 5 and Xbox Series X/S on the same date five years later, December 1, 2020. The game received a Google Stadia port on June 30, 2021, and an Amazon Luna port in January 2022.

The game's primary gameplay modes entail players assuming the roles of attackers or defenders and coordinating with one another to achieve objectives like rescuing hostages, defusing bombs, and control rooms. Environmental destruction plays a significant role in the game. Although it lacks a campaign, it does include a series of brief, offline missions known as "situations," which can be played solo. These missions have a basic storyline and center around recruits undergoing training in preparation for future encounters with the "White Masks," a terrorist organization that poses a threat to the world's safety.

Rainbow Six Siege is a game in the Rainbow Six series that followed Tom Clancy's Rainbow 6: Patriots, a tactical shooter that focused more on storytelling. After the Patriots were scrapped due to technical issues, Ubisoft decided to reboot the franchise. The development team analyzed the core elements of the Rainbow Six series and concluded that allowing players to assume the roles of top counter-terrorist operatives from around the world would be the most fitting approach. To create authentic siege situations, the team consulted real-life counter-terrorism units and studied actual sieges, including the 1980 Iranian Embassy siege. AnvilNext 2.0 powers the game, and Ubisoft's RealBlast technology enables the creation of destructible environments.

Critics praised Siege for its tense multiplayer and emphasis on tactics. However, the game's progression system and lack of content drew criticism. Despite weak initial sales, the game's player base grew substantially when Ubisoft switched to a "games as a service" model and released several free downloadable content packages. After post-launch updates improved the game, some critics considered Siege to be one of the best modern multiplayer games. Ubisoft collaborated with ESL to transform Siege into an esports game. The game reached over 70 million registered players across all platforms in December 2020. A spin-off game called Rainbow Six Extraction, which features Siege characters was released in January 2022.
