In the God of War series, Kratos can find Gorgon Eyes by looking in secret spots and opening hidden chests. Upon finding six (or five in God of War: Chains of Olympus and God of War: Ghost of Sparta), Kratos can make a sacrifice to the gods and increase his health meter, as well as heal any damage he may have at the moment. After Kratos finds a total of 18 Gorgon Eyes (15 in Chains of Olympus and Ghost of Sparta), he won't be able to find anymore as his health meter will be fully reached. In God of War: Betrayal, each single Eye increases the health level. In God of War III, only three eyes are required to increase Kratos' health.
