When you sit down to play a Metal Gear Solid game, I can’t promise you a coherent story or streamlined gameplay. I can, however, promise you tons of Easter eggs as a reward for deep exploration.

Case in point: The radio broadcast featured in the video above. If you don’t own a PlayStation 4, it might not be familiar to you. It’s the radio broadcast that plays on the radio in P.T., the demo for the now-canned Silent Hills.

The broadcast, which describes some pretty graphic imagery, is lifted directly from the cancelled game and is a nice nod. I haven’t had a chance to dig into Metal Gear Solid V: The Phantom Pain yet, but this is sure to be one of countless secrets and Easter eggs in the game.
