Xbox One owners excited to get their hands on Assassin’s Creed Unity are having a rough couple of hours. This morning Ubisoft formally announced that the game’s release date was being delayed into November.

Officially, Assassin’s Creed Unity will now launch on November 11th. Ubisoft, the game’s developer and publisher acknowledged issues with the game’s development, saying it needed a “bit more time to hone some of the details to make sure Assassin’s Creed Unity is exceptional.” Ubisoft didn’t share what parts of the game needed the extra work.

Even as far as blockbuster titles go, delaying Assassin’s Creed Unity for just two weeks seems strange. On one hand, if the title wasn’t done and Ubisoft needed time to get it right,the developer should be praised for not releasing a broken game. On the other hand, two weeks doesn’t sound like enough to fix anything big enough to delay the game.

Joining Assassin’s Creed Unity on November 11th are Halo: The Master Chief Collection and Assassin’s Creed Rogue. Assassin’s Creed Rogue takes place in the Americas unlike Assassin’s Creed Unity. Rogue is being specifically made for the Xbox 360 and PS3, it won’t come to the Xbox One.
