has been delayed by two weeks, Ubisoft announced today. The , , and game is now expected to launch on November 11 alongside for and . Previously, Assassin’s Creed Unity was scheduled to debut on October 28.

Ubisoft senior communications manager Gary Steinman explained on the that the developer needed more time to fine-tune and polish “little things” before the game is ready.

“A tiny gesture that Arno makes as he’s racing across the Parisian rooftops. A barely noticeable reaction from a solitary NPC in a crowd 3,000 deep. The subtle swaying motion of an opulent chandelier in a lavish ballroom,” he said. “It’s these little things, multiplied by the thousands, that a development team focuses on during the final push to ship a game. And with a massive open-world title like Assassin’s Creed Unity, all those little things add up fast. Toss in the fact that Unity has been built from the ground up as a new-gen Assassin’s Creed–and that final straight-line sprint to the finish suddenly feels like an obstacle course laden with curves, hurdles, and pitfalls.”

For his part, Assassin’s Creed Unity senior producer Vincent Pontbriand said making a game from the ground up for new consoles has been a challenge. “This being a fully next-gen game, it requires a lot of work, a lot of production, and a lot of learning,” he said. “It’s always hard to be precise and to quantify exactly how much work is involved. So as we get close to the finish we often realize we’re near the target but we’re not quite there yet.”

Ubisoft will continue to work on Assassin’s Creed Unity up until launch day, culminating with a day-one patch that will offer “even more improvements” to the game. “We honestly appreciate their commitment to the game and their patience,” Pontbriand said. “It’s just a couple more weeks. And it’s going to be worth it.”
