This perk will highlight all hostile enemies in red while you are "actively aiming". This means using iron-sights, a scope, or night-vision scope. Enemies will glow green instead of red when using a night-vision scope. This makes enemies easier to spot and attack, especially at long distances or at night. This perk does not highlight cloaked enemies, such as nightkin.
- This perk and ED-E's Enhanced Sensors perk work well with each other. ED-E's Enhanced Sensors will pick out enemies from further away than your normal compass.
