He's also known for being something of a Five Nights At Freddy's whiz kid (to the point where other Youtubers have called him for help with their lets plays).
Some of his best videos (and series), at least according to me, include:
- Baking Simulator
- Surgeon Simulator
- Octodad: Dadliest Catch
- The Floor Is Jelly
- Windlands (for the Oculus Rift!)
- Drunk Minecraft
Anyway, yeah, that's Markiplier (although these are mostly humorous games, seen as I'm not super into the scary stuff hehe).
