God of War is an action-adventure video game series loosely based on Greek mythology. The series' story centers around its playable character, Kratos, a Spartan warrior tricked into killing his wife and daughter by his former master, the God of War Ares. Kratos kills Ares at the behest of the goddess Athena and takes his place as the new God of War, but is still haunted by the nightmares of his past. Revealed to be a demigod and the son of Zeus, the King of the Olympian Gods who betrays Kratos, the Spartan then seeks revenge against the gods for their machinations. What follows is a series of attempts to free himself from the influence of the gods and the Titans and exact revenge.
