Sony showcased all-new gameplay footage for the upcoming God of War reboot, which is bringing back protagonist and antihero Kratos and the franchise’s signature brutal hack-and-slash combat to a new Norse mythology setting. This God of War reboot, from Sony’s Santa Monica Studio, was first announced at the company’s E3 press conference last year. We knew then that the franchise would be transitioning from Greek mythology to ancient Norse myths, with a renewed focus on Kratos’ relationship with his apparent son Atreus.

In an exciting potential hint at the nature of the game’s narrative, the new trailer ended with Kratos and Atreus meeting a giant sea serpent that could very well be Jörmungandr, one of Loki’s three children and an instrumental player in the bringing about of Ragnarök, Norse mythology’s apocalyptic event. This bodes well for theories that Atreus is secretly an enemy of thunder god Thor, possibly the living embodiment of Ragnarök. In other words, despite his new softer demeanor, Kratos might continue to serve as an antihero who’s working against the protectors of the known universe as he did in the original trilogy.
