How the enemies think

Patrol -> Suspicious (?) -> Investigate -> back to Patrol Patrol -> sees the player long enough -> Chase -> Attack Chase -> loses the player -> Search -> back to Patrol

• Sight: a view cone with a line of sight check. It needs a moment to be sure (awareness grows faster when you are close). Very close, it notices you even from behind.
• Hearing: running, walking and shots make noise (Noise). Walls make the noise quieter. Enemies walk to the place they heard it.
• Allies: an enemy that spots you or gets shot alerts the enemies near it.
• Two kinds: a melee grunt (wind-up before the hit, so you can step away) and a shooter that fires from a distance with some spread.
• Headshots do more damage. Every enemy shows its state and health above its head.
• Select an enemy in the Scene view to see its view cone.
