There is a rumor online that Ubisoft has cut the team that previously created and released the metroidvania Prince Of Persia: The Lost Crown.
Thus, we can conclude that the game will definitely not have a sequel. Yes, the project was not a hit, but it did have fans. However, this was not enough for the franchise to receive a budget for further development. The original game will receive the previously promised add-on, but fans should not expect more.
Prince Of Persia: The Lost Crown is available on PC and consoles.
