UPDATE: It’s official. Xbox and Ubisoft have confirmed thatRainbow Six Siegeis coming to Game Passon October 22.

Original story follows.

Xbox Game Passcontinues to offer plenty of value for gamers, with the service consistently updated to offer more new games to jump into. The latest addition toGame Pass, if a recent tease is anything to go by, is a major multiplayer game from Ubisoft.

Though Microsoft just recently announcedthe addition of LucasArts remasters likeGrim Fandangoto Game Pass, the company wasted no time teasing what is coming next to the platform. The official Xbox Game Pass Twitter account posted an image with no text that featured a castle and a rainbow, a seemingly random and confusing post from the account. Fans were quick to realize that there was more to see in the image, however.

Rather than being a tease for one of thepreviously announced games coming to Game Pass, it’s possible the teaser is for an entirely new addition. Rather than looking at the castle and rainbow portion of image, a look outside the castle showcases a group of knights preparing trebuchets. With that in mind, it does not take long to recognize that the soldiers outside are preparing to attack the castle in a siege. From there, fans have deciphered that the clever teaser is forRainbow Six Siege.

Ubisoft seems to be doing everything it can to keepRainbow Six Siegetalked about among series fans, as it recentlybroughtSplinter Cellprotagonist Sam Fisher toSiegeas part of September’s Shadow Legacy operation. With a three-player co-op spinoff on the way called Quarantine, which aims to put a terrifying twist on theRainbow Sixformula, the series does not seem to be going anywhere anytime soon. A release on Xbox Games Pass could be a perfect opportunity for players to catch up on the new content added toSiege, bringing in new players for Ubisoft in the process.

Rainbow Six Siegeis out now for PC, PS4, and Xbox One.
