GO TO THE LEFT CORNER OF THE GATE AND ANGLE YOUR CAMERA ABOVE YOU SO THAT THE GATE IS ON THE RIGHT
KEEP JUMPING AT THE CORNER UNTIL YOU START SHAKING, AFTER YOU SEE THE SHAKES JUST HOLD FORWARD TO CLIP INTO THE WALL
ONCE INSIDE WALK COUPLE STEPS UP AND JUMP OVER A HOLE AND GO UP RIGHT INTO THE LOADING ZONE
