Rainbow Six: Siege has been delayed into December for further adjustments and improvements

Rainbow Six: Siege has been delayed into December, Ubisoft has announced.

The delay is due to feedback received and based on our own internal tests.

"We felt there are adjustments and improvements we can make, including improving the co-op experience across all game modes, weapon and gadget balancing, as well as menu and interface navigation," said the firm.

"We’re taking a little more time to make these changes, and we think it’s the right call."

The closed beta for Rainbow Six: Siege will still start on September 24 as planned, and the additional time will allow for further testing on the infrastructure and matchmaking.

It will now be released on December 1.

Rainbow Six: Siege was originally slated for release on PC, PS4 and Xbox One on October 13.

If you pre-order on Xbox One, you get instant access to the Xbox 360 versions of Rainbow Six Vegas and Vegas 2 via backwards compatibility.
