Although Sony released a trailer for God of War: Ascension, they since hasn't revealed any other information on the new game. The trailer points to a possible prequel: images of Kratos bound in chains as a voice says "a time before Kratos became the monster known as the Ghost of Sparta." In the final moments of the trailer, Kratos breaks free from his chains while a voice proclaims: "A time when he would break his blood oath to an unjust god, a time when he would no longer be bound in blood." The trailer ends with an image of the PS3.

Sony first hinted at an upcoming teaser for a new God of War game earlier, posting an image of Kratos on the official PlayStation Facebook page. In February, retailer BT Games posted a product listing for God of War IV, and a month before that, multimedia composer Timothy Williams indicated he was working on a fourth entry in the franchise. Last year, job listings at Sony Santa Monica called for people to join the God of War development team to create multiplayer services for the franchise, including matchmaking infrastructure and leaderboards. While the new trailer indicates the title will be headed to the PS3, Sony Santa Monica senior director of product development Shannon Studstill said the franchise might head to the PlayStation Vita or mobile platforms.

The game is schedualed to release sometime during spring of 2013.
