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 to the game: offence and defence. Operators on each side differ. The aim of the attackers is to locate two bomb sites and defuse one of them by 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 teams wins seven rounds. If there is a draw at 6:6, three extra rounds are played.
