Rainbow Six Siege's big Operation Para Bellum update is nearly here. Following its recent stint on the Siege test server, Ubisoft has now confirmed when the expansion will roll out for the live game, and it happens very soon.

Operation Para Bellum will go live for all platforms--PS4, Xbox One, and PC--on Thursday, June 7. As is typically the case, those who've purchased the Siege season pass will receive access to Para Bellum's two new Operators, Alibi and Maestro, immediately at launch, while all other players will be able to unlock them one week later, beginning June 14.
