God of War: Ascension's multiplayer powered by Zeus
God of War: Ascension is the first in the franchise to add multiplayer, which is explained away in this trailer by the notion that Zeus, ruler of the pantheon, chooses human champions to battle his enemies. Even though he could presumably smash them himself with the lightning he gave to the mortals. Maybe he has an appointment to keep that day?
You'll notice there are two trailers down there; the second one is a "making of" affair called Unchained, which tracks two years of development as the Sony Santa Monica team build towards God of War Ascension's March 2013 release, exclusively for PlayStation 3.
Thanks, Gematsu.
