It’s a Halloween edition of Conan O’Brien’s Clueless Gamer, and he and Aaron Bleyaert play Slender (“That doesn’t sound scary,” Conan notes, unfamiliar with Slenderman and more fearful of European trucks), Amnesia (“I have amnesia, but I know it’s 1839, my name is Daniel, and I’m in Prussia. Those are questions that if you have amnesia, the first questions they ask you are what year is it, what’s your name, and where are you”), and Outlast (almost as scary as Conan’s colonoscopy video, plus it has a doctor with no pants and there’s a post-mortem shot that Conan finds particularly unfortunate). And they play it all in the dark. Ooooo, scary!

And while we’re at it, here are some Lesser Known Monsters:
