"Hear an alert when an enemy aims at you. Your vision pulses if the enemy is outside of your view."
— In-game description.


Paranoia is a perk featured in Call of Duty: Black Ops 4 and Call of Duty: Black Ops Cold War. It is similar to the High Alert perk from Call of Duty: Modern Warfare and the Perception trait from Call of Duty: Infinite Warfare.

In Black Ops 4, it only appears in the Blackout mode as a pick up item. In Black Ops: Cold War, it appears as a Tier 1 perk in multiplayer.
