God of War is a series of action-adventure video games that made its debut in 2005. The games have their basis in Greek mythology. The player controls Kratos, a human warrior that challenges the gods of Mount Olympus after being used and discarded as one of their tools, during which he unwillingly killed his wife and daughter. To stop Kratos, the gods have unleashed numerous mythological beings, but Kratos is able to overcome these while using magical objects given to him by Athena and the few other gods that are sympathetic to Kratos' plight. Later, Kratos gets his magical objects from the Titans and fallen foes.
