Siren Head is very real. And quite possibly standing right outside your window. But in other news you probably should never go camping because he's coming for you. And when he's coming for you... he will find you. And he will mock you. And then he will eat you...

    Funnily enough in stuff like camping, diving etc it’s often a rule that you should always make sure you’re safe first before helping out someone else so in a lot of cases you have to just get out of there and save your own skin instead of dying alongside your friend (I know it’s an extreme example but whatever)

    This game is honestly genious. The siren noises used were originally purposed to put fear into your head so that you seek saftey in a time of crisis...Using that to the disadvantage of the player is brilliant. Terrifying, but brilliant!

    So this is my first time watching M.P. And I got to say I didn’t like him at first, because I thought he was acting like a child in a adult man body, but he literally is! Which makes him funny, anywho, he explains this game and looks into details which I can understand when he’s playing throughout this game, which makes me the viewer easier to understand, so I guess you could say, I’m a new subscriber. Thank you Mark.
