God of War: Ghost of Sparta
This game starts off with a bit of backstory. Turns out Kratos has a brother, Deimos, who was kidnapped by the gods because of a prophecy that they would be killed by a “marked warrior.” Since Deimos was born with unusual birthmarks, the gods naturally assumed he would be the one to kill them.
Fast forward to the present, and Kratos, the newly-crowned God of War, travels to Atlantis and finds his mother, Callisto. She informs him that Deimos is alive and not well in the clutches of Thanatos, the God of Death. Callisto also tells Kratos about his father (turns out it’s Zeus), which transforms her into a twisted monster that Kratos mercifully kills. Kratos eventually finds Deimos, but their reunion is short-lived, as Thanatos kills Deimos. And then Kratos promptly kills Thanatos. Athena tries to console Kratos by turning him into a full-on god, but that only ends up pissing him off even more.
