It is not uncommon for a game is canceled before it is even announced. Imagine that of projects that we will never know because they did not exceed the internal expectations of the company. The one that concerns us today could be classified as such, but something curious has happened.
It turns out that Prince of persia
Guided by the title of the video, this canceled installment was to be called Prince of Persia: Redemption. What you can see there is not a trailer published by Ubisoft, much less, but a full-blown leak that he managed to bypass all radars (the opposite of what the leaks intend, everything to be said). The game was never even announced.
Well, actually someone did. Best of all, the video has a comment published two years ago
The truth is that what you see in the video it's not bad at all. Lots of parkour, action and time-manipulating mechanics typical of the franchise. The staging is spectacular even today, and that is a PS3 and Xbox 360 game.
