Metacritic Score: 87.25
Considered one of the most critically successful games from Capcom, Resident Evil 4 changed the franchise entirely with an introduction of a new style to the third-person survival horror series. Zombies that have thought and use weapons is a scary idea indeed. The game went on to receive numerous Game of the Year awards, and many definitely consider it as one of the 11 best zombie video games of all time.
