How do I play the prince of persia epilogue?

you have to go to the “Extras” section… there you should have the option to play the epilogue. Enjoy it!

It’s a freestanding chapter, meaning that it doesn’t have anything to do with lightseed collecting or your previous progress in the main game.

I have an Xbox 360 and the option to play Epiloge was not under Extras, it was instead in the Bonus Content area. Once I selected that, the only option I had was to select Epilogue. Took me like 5 minutes to find it though, hope this helps someone. ;D*
