Ubisoft has pushed back Assassin's Creed Unity's release date by two weeks.
The publisher announced on Thursday that the latest title in the open-world assassination series will release on November 11 in North America and November 13 in Europe.
"This being a fully next-gen game, it requires a lot of work, a lot of production, and a lot of learning," senior Vincent Pontbriand said in a post on the Ubiblog.
"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."
The post also noted that the team will continue working past shipment time to prepare a Day 1 patch "that offers even more improvements to Unity". The game is planned for release on PC, PS4 and Xbox One.
An Assassin's Creed Unity challenge mode featuring what appeared to be playable versions of characters from previous series entries seemingly leaked earlier this week.
