About

ABYSS Deep Light

Read full description

ABYSS โ€“ Deep Light In total darkness, you are the last spark of light. Dive ever deeper into the abyss and bring the light back. STAND STILL TO SHINE Hold still and your submarine lights up, revealing the creatures of the deep and opening fire โ€” but it drains your energy. Move, and you stay hidden in the dark and recharge. This rhythm of shining and hiding is the heart of ABYSS. OXYGEN IS YOUR CLOCK Your air runs out constantly. Collect bubbles and surface in time โ€” running empty is deadly. THE DEEP PASSAGE Narrow rock shafts where currents pull at your boat. Steer through sluggish inertia, dodge the walls, gather light and air โ€” and choose the right route. EVER DEEPER, EVER STRANGER Layer by layer the deep grows darker and more dangerous. New guardians awaken, new creatures lurk โ€” until something ancient waits at the very bottom: the Source of the darkness. ONE REPAIR KIT You receive exactly one emergency rescue. Save it โ€” use it too early and reaching the end becomes almost impossible. REPUTATION & RANK Every enemy raises your reputation; a forced surfacing lowers it. Rise from deckhand to a legend of the deep. THE SHIPYARD Trade salvage for permanent upgrades: armor, light, oxygen, propulsion. You will only reach the depths well equipped. FAIR BY DESIGN No pay-to-win. No ads. A premium game you beat with skill โ€” not your wallet. German & English, always with subtitles.
