It appears that the release date for Tom Clancy’s Rainbow Six Siege has been leaked for October 16th. The Gamestop Italy site seems to have prematurely leaked the date before changing it to its current state of “to be determined”. Users can currently register for the game’s beta by either pre ordering the game or registering online at the game’s site. You can take a look at the leaked image below and we’ve reached out to Ubisoft for clarification.
