9 Hidden Video Game Enemies You Weren't Supposed To See

9. Kaernk - Amnesia: The Dark Descent

Starting off with the most obvious embodiment of the title I can think of, the Kaernk in seminal horror game Amnesia: The Dark Descent is literally an invisible monster. Showing up in the waterway levels, this beast is only identified by the splashes it makes in the water, with the player being forced to use these visual and audio cues to avoid it at all costs.

The whole point of Amnesia is what's just lurking out of sight, with the game even punishing you for staring too intently at any of the monsters. An invisible enemy like this then is perfect, and proved to be one of the scariest things in the whole game.

Of course, the mystery of the creature only led to fans eager to know what it would look like if it could be seen by the human eye. It clearly has a defined mass, so it much have a shape, right?

Well, concept art actually revealed what the Kaernk would have looked like, and essentially it's a big creepy monster dolphin. Pretty cool.
