Assassin's Creed 4: Black Flag, still to this day the greatest in Ubisoft's sandbox Assassin's Creed 4 Black Flag has disappeared from Valve's storefront, and also been removed from the Steam Assassin's Creed bundle.
As Assassin's Creed Mirage release date as well as multiplayer-based AC Infinity and Assassin's Creed Red, set in Japan.

As of Thursday, September 7, Assassin's Creed 4: Black Flag is not available to buy on Steam. The game has also been removed from the Assassin's Creed bundle which includes every other mainline entry in the open-world game series.
However, Black Flag is still available from the Ubisoft Store, and its removal from Steam does not necessarily have a connection to a pending remake – games may be temporarily delisted as developers resolve technical issues or introduce large-scale updates.
On the contrary, the original version of Assassin's Creed 3 has been removed from Steam, to be replaced by the remastered edition from 2019. The sheer optimist in me wants to say that Ubisoft – no pun intended – is clearing the decks for the arrival of a Black Flag remake, but one has to temper one's expectations.
PCGamesN has ed Ubisoft about the removal of Assassin's Creed 4 from Steam and will update this story with any comment or further information.
