It's no wonder the game's been as popular as it has.

Resident Evil 4 is a gripping survival horror game played in an over-the-shoulder style, credited with inspiring TPS titans like Gears of War. Not all the editions flourished, but since it's widely considered the best game of all time, a plethora of platforms have been made compatible. Resident Evil 4 has been ported numerous times since its original release in January 2005.
