Rainbow Six Siege fans will have to wait even longer for the full game to come out.
Ubisoft's upcoming first-person shooter, which was initially set to debut in October, is now pencilled in for a December 1 launch across all regions.
"This wasn't an easy decision, but based on the feedback we've 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," Ubisoft said in an update on the Ubi Blog.
"We're taking a little more time to make these changes, and we think it's the right call."
Ubisoft has also confirmed that the closed beta for Rainbow Six Siege still start on September 24 as planned.
The publisher added: "The additional time will allow us to further test things like infrastructure and matchmaking.
"That extra testing and added polish will make for a higher-quality experience at launch."
Announced during E3 2014, Rainbow Six Siege features five-on-five battles on close-quarters maps with highly destructible environments.
It also marks the return of the TerroHunt mode, which allows for solo or cooperative play with up to four additional teammates.
