You know that Challenge of Hades that you unlock after beating the game once...
Well if your up for the challenge then it is right for you...
After beating the game the God mode is also unlocked...But it is extremely hard because you inflict less damage ut take more damage from enemy attacks so be careful...
The funside of the game is when you unlock all the costumes...It gives special abilities to Kratos...It is like a God of War with Cheat...
But if you're asking about those lost levels,I don't actually know if they do exist or if they are in the game...
Hope this Info helped a bit...
