Invisibles throws you into a world where traditional vision is unreliable. You won't see your enemies directly, but their actions leave signs in the environment. These signs can be:

Sound: Gunfire, footsteps, – listen closely to pinpoint the enemy's location and movement.
Visual: Muzzle flashes, gun laser, and other player's exposed shape (when they run out of shield).
Environmental: swaying doors, flashing lights, and footprints.

Think before you shoot:

Loudness is deadly: Firing your weapon exposes your location to everyone. Choose your shots wisely.
Adapt and overcome: enemies leave different signs. Learn to read the environment and predict enemy behavior.
