Silent Hill: Book of Memories - Farm XP (Fail Combo Challenges)

All zones after the final story zone (Zone 21) are randomly generated including the Blue Orb challenges. There is a rare «4x Combo» challenge which you can use to Farm XP by failing the challenge and allowing the enemies to continuously respawn. Using the weapon «Princess Heart» (available in DLC: Extra Memories) can speed up this process. I am simply alternating between hands by holding SQUARE (Left Hand) and then TRIANGLE (Right Hand) and spamming L1 to Lock-On to targets. It's highly recommended that you save and exit regularly as the game will eventually crash with «memory allocation» errors. Also when I first started this challenge there was a «Butcher» and «Pyramid Head», after a few reloads they stopped respawning and just spawned «Nurses» as shown in the video.
