10 Invisible Enemies That Made You Rage Quit

10. The Kaernk - Amnesia: The Dark Descent (2010)

Fifteen years after its initial release, Frictional Games' Amnesia: The Dark Descent remains one of the most terrifying horror games ever made. The pitch-perfect atmosphere kept players in a constant state of suspense as they explored Brennenburg Castle's foreboding hallways, never knowing what was waiting for them in the darkness.

One of this game's most harrowing sequences is found within a flooded area of the cellar. Upon entering, the sound of approaching splashes tells players that they're not alone. The source of these watery footsteps is the Kaernk, an invisible monster that attacks players whenever they're in the water.

The goal here is to find the levers to open the doors to the exit. Being unable to stay in the water, though, players must dash between crates scattered throughout the area to avoid becoming the monster's next meal.

With only a few seconds to reach safety each time players are forced to step into the water, this sequence is full of narrow escapes that are too close for comfort.

The relentless terror tests the nerves of any horror fan. However, by hitting the Kaernk with a crate or barrel, players can exploit a bug that stops it in its tracks, effectively killing it.
