Prelude in Violet/Perk-a-Cola/Raven's Eye

Raven's Eye is a Perk-a-Cola introduced in Prelude in Violet through the map Schule für die Untoten. The perk adds new HUD indicators that appear when an enemy approaches from out of the player's line-of-sight. These indicators initially appear as barely visible and translucent light gray arrows, getting brighter and opaque as enemies get closer before appearing a visible bright white. If enemies outside of the player's sight line are close, the player's movement speed is increased by 33% for the next 15 seconds with a minute cooldown after. Should the player be hit be an enemy from out of sight, the player gets a 50% increase to their movement speed for 10 seconds with a minute cooldown. Raven's Eye has a steep price of 3500 points.
