The live action video focuses on the family of angry protagonist Kratos and is set to air during Super Bowl 2013.
Senior brand manager Anthony Caiazzo said of the trailer: "I'm extremely excited to share with you the full length version of our 'From Ashes' live action trailer featuring a special arrangement of Ellie Goulding's 'Hanging On'.
"This is just about the biggest production we've ever undertaken for a God of War commercial or trailer, or for any PS3 game for that matter. We are very proud of how it turned out, and hope you enjoy watching it as much as we enjoyed making it."
Earlier today a plethora of new God of War: Ascension media appeared online, including the PS3 game's opening 30 minutes.
The God of War: Ascension release date is set for March 15 in the UK and March 12 in the US.
