You're stranded alone in the pitch-black depths of the ocean. Your only weapon is a single beam of light.
Tap the screen to control the 30° fan-shaped beam. Enemies hidden in the darkness are revealed only when illuminated by the light, and only defeated when struck by it. However, the beam consumes energy. When energy runs out, the screen goes dark for two seconds—during which enemies pour in.
Choose from over 30 upgrades every five waves. Choose from options like the Glass Cannon, which doubles beam damage but leaves you with only one life, or the Frenzy, which becomes more powerful the lower your energy is. These risk-reward choices create a tense atmosphere. Combining two upgrades unlocks hidden synergies.
Over 12 enemies, three bosses, elite variants, and environmental events will challenge you as you descend deeper into the abyss. Experience a unique experience every time with permanent upgrades, daily challenges, over 30 achievements, and five beam weapons.
How long can you last in the abyss?
Survive the darkness of the deep sea with only one light. Control your beam to defeat enemies in this one-touch survival arcade game.
