The announcement was saved for the finale of Wednesday’s PS5 showcase.
In Norse mythology, Ragnarök is the ultimate destruction of the gods in a cataclysmic battle with evil, out of which a new order will arise.
“The time draws near,” series protagonist Kratos says in the teaser announcement. “You must prepare yourself.”
Unlike previous entries in the long-running series, which were inspired by Greek mythology, God of War is loosely based on Norse mythology.
The series reboot was a critical and commercial success, winning multiple Game of the Year awards and selling over 10 million copies.
Sony released a two-hour documentary detailing the development of God of War in 2019.
