Assassin’s Creed 4 will be released in late October this year and it looks like you shouldn’t have to wait any longer than November for the PC port. AC4:Black Flag’s game director, Ashraf Ismali promised that the game’s PC release will come only “a few weeks after” the Xbox 360/PS3 console releases.
Ismail noted that Ubisoft Montreal are already working hard on the PC release and assured, “for our PC fans, don’t worry. The game on PC looks phenomenal.”
This would hopefully calm some fans who had issues with the technical and graphical bugs that plagued the pre-patched versions of Assassin’s Creed 3.
AC4:Black Flag will be released on October 29th in the US, November 1st in the UK, but Ismail has said that he might be wrong about the PC release window but stated “it might actually be sooner if [he's] wrong.”
The game’s PS4 and Xbox One release dates have not been announced but are expected to be within the launch window of the console unit launches.
