Rainbow Six Siege is a 3D action first-person game. Teams of five players fight on different maps. Every player chooses one of the different operators with unique weapons and abilities.
There are two sides in the game: offense and defense. Operators on each side differ. The aim of attackers is to locate two bombsites and defuse one of them be holding a defuse kit near the bomb for some time. If any defender is in range, the defuse will not happen. After each round, teams switch the sides and go on until one of the team wins seven rounds. If there is a draw 6:6, three extra rounds are played.
