Abyssal trench where only darkness is safe: towers fire only outside your floodlight radius, and light attracts elite stalkers. Balance seeing the map against weaponizing the dark. Signature: kill the lights during a stalker wave, then re-illuminate to snipe.
Void navy to black gradients, cyan and violet creature glow, floating marine snow, single-point light cones.
Click, Enter or Space to start. Place and upgrade towers with the mouse and number keys, or by tapping on touch, to stop each enemy wave before it reaches your goal. The HUD tracks lives, cash and wave.
