During the Credits
Videos of Kratos from the game are shown alongside the credits of God of War. The credits slowly zoom out to reveal a mosaic of Kratos made from the videos.
After the Credits (spoilers)
There is a message that says, “Kratos Will Return” after the credits. There are also lots of extra special features unlocked after completion of the game including videos explaining what happens to characters after the game and even more information about Kratos’ mother, brother and father.
