Rainbow Six Siege is an adept mix of first-person shooting, strategic planning, and tactical teamwork. Two teams of five vie for control of a building, where the goal is to capture an objective, defuse a bomb, or secure a hostage. The brilliance of Siege comes in learning these buildings in and out and knowing how to work with your teammates to get in and out most effectively. Map knowledge can trump twitch shooting in the most dire of situations, rewarding its players for smart thinking and careful play.
