The God of War background story is centered around Kratos. Kratos was a mortal man who became a weapon for the gods. His life took a tragic turn when he killed his family under the influence of Ares. This led to his quest for revenge. Throughout the series, we see him grow from a simple warrior seeking vengeance to a more complex character who is trying to break free from the cycle of violence and the control of the gods. He travels through different realms, battles numerous mythological creatures, and challenges the very gods who once used him. His story is one of tragedy, growth, and the search for meaning in a world ruled by the divine.
