When it comes to breaking the fourth wall, Hideo Kojimas usually the first to grab a pickaxe. His games are rife with clever Easter Eggs and sequences that explore the notion of playing a game elsewhere in Metal Gear Solid, Psycho Mantis will freak out the player by reading the contents of their memory card and making their controller rumble. Partway through his mission, Snake needs to contact Meryl, one of his allies, for some information. To find the frequency they need to reach her, the players told to look on the back of the CD case. The player has something in their inventory that might loosely qualify, but theres nothing on the back that can be used to solve the puzzle. As it turns out, its an obscure clue - the player needs to examine the case that the game itself came in, where Meryls codec frequency is shown in a screenshot on the back of the box. Whether this was an experimental puzzle, an attempt to foil game pirates or just Kojima having a laugh is uncertain, but anyone borrowing or renting the game was left utterly stumped. Even today this question continues to baffle players the games been rereleased as a digital download, meaning that there is no CD case to examine. Anyone desperately seeking Meryl can nose around in the games digital manual for the answer, but the satisfaction of solving the puzzle properly has, unfortunately, been lost to time.
