If you are a hardcore Tom Clancy fan (who isn't?) and waiting patiently for the upcoming title from Ubisoft called Rainbow Six siege, then you are seriously set for some bad news.

According to reports, Ubisoft has decided to push the official release date for Rainbow Six Siege to 1 December.

Rainbow Six Siege, the multiplayer-focused shooter, which was previously due to be released on 13 October, was previously shown at two of the year's biggest gaming events – E3 and Gamescom.

The company wrote on its official Ubisoft blog: "We've decided to push the release date of Rainbow Six Siege to December 1, 2015 for 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. We're taking a little more time to make these changes, and we think it's the right call," it added.

However, as planned, the closed beta for the game will still start on 24 September, 2015. "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," the blog post read.

"We understand that many of you are excited to get your hands on the final game, but as gamers ourselves we know that quality comes first and we are committed to delivering the best game possible," the blog post added. 

Stay tuned for more updates!
