Valkyrie Studio has posted a fresh vacancy for an environment artist, from which users have concluded that a new part of the God of War series is in the works. The fact is that this organization helps Sony Santa Monica in the implementation of a lot of graphic tasks, and in the description of the vacancy itself it is indicated that the team is now working on some new iteration of the legendary franchise.
It is not yet clear what the new game will be about, as the developers have previously noted that Ragnarok completes the narrative of Kratos and Atreus. Perhaps we are talking about a spin-off about some other character who appeared (or did not appear) in one of the parts of the series.
In any case, there is still a long wait for official news, and the company's plans can change at any time.
