God of War didnt invent powered-up states in hack & slash games, though the series is the reason many of them use L3+R3 to activate them. Each game introduced a different take on this Rage state, whether it was the original games Rage of the Gods, GoW2s improved Rage of the Titans, or GoW3s fiddlier Rage of Sparta. Then the 2018 God of War game changed everything, from the Norse setting to the new, up-close combat.
