10 Hidden Video Game Characters You Weren’t Supposed To See

Metal Gear Solid and background secrets go together like infiltration and cardboard boxes.

In Sons of Liberty, we are introduced to Vamp. One of the members of the villainous Dead Cell, his particular gimmick was immortality which is a pretty neat trick to have on your side. Because of this, it was difficult to suspend our belief too much that the boss fight against him actually resulted in the character meeting his untimely end. Especially considering that Vamp had been shot in the head numerous times already, of course. Vamp returned five years later during the events of Metal Gear Solid 4: Guns of the Patriots to have another showdown with Snake.

Insanely eagle-eyed players may have seen this coming however if they paid very, very close attention to the final cutscenes of Metal Gear Solid 2. As Snake and Raiden stand outside Federal Hall and wax lyrical about philosophy and politics - it is a Metal Gear title, after all - Vamp can actually be spotted in the crowd around them at multiple points, albeit for just a few milliseconds.

But that could be any handsome devil in a big brown duster, right? Well, thanks to fan hacked camera tricks we know that it is indeed Vamp. Proving that he was still alive, and would be returning in the future.
