Doubles the cooldown timer

The cooldown timers are significantly increased the bigger your Pursuit Level is. You'll have a tough time escaping a Level 4 Pursuit. Also, going Underwater no longer helps you escape.

The Cooldown timers are infinite. Once initiated, the Pursuit will only end when you enter a Safehouse or survive until sunrise. Otherwise, the Infected will keep searching for you. Needless to say going Underwater will only help you enter Cooldown mode.

The cooldown timer isn't even triggered. The pursuers will be permanently aware of your position, thus the edge of the minimap will be permanently red, unless you enter a safehouse or survive until daytime.
