The footage introduces the Furies, female chthonic deities of vengeance seeking to punish Kratos for breaking his contract with Ares.
Much like the upcoming God of War movie, Ascension will present a more human side of Kratos, set in a time before his desire for vengeance consumed him.
The storyline takes place before the events of the first God of War and sees the Ghost of Sparta attempt to break free of Ares's bonds.
Announced earlier this year, the upcoming prequel will be the first entry in the series to include multiplayer support, enabling up to eight players to compete in a variety of game modes and customise their characters.
God of War: Ascension will be released for PlayStation 3 on March 12, 2013 in North America.
