Tom Clancy's Rainbow Six: Extraction (originally known as Rainbow Six Quarantine) is a follow-up to Tom Clancy's Rainbow Six series, this time focusing on co-op between three players trying to eliminate a deadly parasite of unknown origin. Game was developed by Ubisoft Montreal studio. In the game we play as one of the soldiers sent on missions to get information about the parasite of unknown origin. In the game world, a meteorite crashed on Earth, which started a cycle of strange events; Rainbow Six agents were sent to combat the threat. Three years later, the parasite reappears, constantly evolving and mutating and posing an even greater threat, overwhelming even the Special Forces Operators. In Extraction we won't find a full-fledged single-player campaign, but during the game we complete a special Codex that contains additional information about the game world and the mysterious parasite.
