the "mystery blade" is the blade of Olympus from the second game. Which is activated when a "rage meter" fills for Kratos. Also the barbarian hammer doesn't return, its a new hammer from one of the mini bosses you fight. I don't know if you get it as a weapon, but you use it to kill the stone thing, as a finishing move.

Go rent it, if you like it, buy the fucking thing, play it to shit and take the critism for buying a poorly rated game, as most other people will be having 'fun' with their brainwashing highly rated game, whereas you have a gaming 'experience' with your low rated supposedly 'shit' game!
