Some enemies are able to see through disguises and can be alerted if the player enters their vision, and all enemies can be alerted to suspicious behaviour which includes picking the lock of a door or looking through a door's keyhole, being in certain stances, or having certain weapons visible.
Adversaries are capable of detecting disguises and becoming aware when the player enters their field of vision. Any enemy can be notified about suspicious behavior, such as attempting to pick a door's lock, peering through a keyhole, maintaining specific stances, or displaying certain visible weapons.
