Tom Clancy's Rainbow Six Siege

Developed and published by Ubisoft, Rainbow Six Siege is an online tactical shooter video game that emphasizes environmental destruction and teamwork. It was released worldwide for PlayStation 4, Windows, and Xbox One on December 1, 2015, and later for PlayStation 5 and Xbox Series X and Series S on the same date five years later. Siege has various gameplay modes, including rescuing hostages, defusing bombs, and taking control of objectives, with each player assuming the role of either an attacker or defender.

The game features short offline missions called "situations" with a loose narrative that focuses on recruits preparing to face the "White Masks," a terrorist group. Siege is a reboot of the Rainbow Six franchise, following the cancellation of Tom Clancy's Rainbow 6: Patriots. The game allows players to impersonate top counter-terrorist operatives and create authentic siege situations, thanks to consultation with real-life counter-terrorism units and examples of real sieges.

Siege uses AnvilNext 2.0 and Ubisoft's RealBlast technology to create destructible environments. The game has since been ported to Google Stadia and Amazon Luna. Critics generally gave the game positive reviews, especially for its intense multiplayer and tactical focus, but criticized its progression system and lack of content.

Despite weak initial sales, the game's player base grew substantially after Ubisoft shifted to a "games as a service" model and released multiple packages of free downloadable content. Over time, Siege became one of the top multiplayer games in the industry, thanks in part to post-launch updates. Ubisoft also partnered with ESL to establish Siege as an esports game. As of December 2020, the game had over 70 million registered players across all platforms. In January 2022, a spin-off game called Rainbow Six Extraction, featuring characters from Siege was released.

Tom Clancy's Rainbow Six Siege Gameplay

Tom Clancy's Rainbow Six Siege is a first-person shooter game that allows players to select from different operators belonging to the Rainbow team. These operators come from various nationalities and have unique weapons and gadgets. The game employs an asymmetrical structure, meaning that teams don't have balanced abilities. The available Counter-Terrorism Units (CTUs) include the American Hostage Rescue Team (FBI SWAT), British SAS, German GSG-9, Russian Spetsnaz, and French GIGN.

Each unit has four operators per team, divided between attackers and defenders. The game also has a "Recruit" operator who can choose from a flexible range of equipment but lacks a unique gadget or weapon customization ability. Players select their operator and spawn points before a round begins, but once it starts, they cannot change their choices.

Players can earn in-game currency, "Renown," for actions performed in the game and can use it to purchase operators or cosmetics from the in-game shop. The renown earned varies depending on the gameplay mode, with ranked matches offering the largest multiplier potential per match. In addition, players can complete in-game challenges to earn small amounts of renown. Renown gain rate can be increased by using "boosters" that give the player a boost in all renown earned for a specific duration, starting from 24 hours. Players can also purchase a premium currency called "R6 credits" using real-world money to unlock operators or other cosmetic items like weapons or operator skins. 

In Tom Clancy's Rainbow Six Siege, players choose from a variety of operators with unique nationalities, weapons, and gadgets to participate in an online match with an asymmetrical structure. Before the round starts, attackers and defenders each chooses a spawn point to launch their attack or defend from, respectively. A one-minute preparation phase begins, during which attackers can control mecanum-wheeled drones to scout the map, while defenders establish their defenses without revealing details to the opposing team.

Maps in the game are designed to promote close-quarters combat, and players cannot respawn until the end of the round. However, players who were killed can enter "Support Mode" and continue to contribute to their team. Matches last four minutes for casual and three minutes for ranked play. Siege emphasizes teamwork and communication between players, who must utilize their different abilities to complete the objective and defeat the enemy team.
