The game hit Microsoft's older console in late October before the next-gen version was released on November 22.
In CVG's Assassin's Creed 4: Black Flag review our critic said the sequel marks a return to form for the franchise, noting:
"The fact that ACIV is so good was by no means a foregone conclusion. There was a sense that, as the dust settled after ACIII, Ubisoft had missed a beat. Brows rightly furrowed as commentators pondered whether the series had already overshot its zenith. Much like the first Assassin's Creed, Black Flag isn't perfect. But the treasure trove of memorable experiences on offer here put all but the very best open worlds to shame."
