Tom Clancy's Rainbow Six: Siege (Ubisoft)

Tom Clancy's Rainbow Six Siege is inspired by the activities of real-life counter-terrorist organizations and brings players into the center of deadly melee combat. For the first time in Tom Clancy's Rainbow Six, players can choose from a variety of unique counter-terrorist operatives and engage in tangible sieges, a new style of assault in which enemies are allowed to turn their surroundings into modern strongholds, and Rainbow Six teams lead the assault to break through enemy positions.
