Abyss Cave

Abyss Cave is about an elite squad sent by DarkStar Academy of Sciences into a colossal cave after researchers there lose contact with the surface. A strong energy disrupts the squad soon after they enter: its members fall unconscious and their Drilling Trucks go out of control. You wake in the deepest part of the cave, tens of thousands of meters underground, with your truck badly damaged and many of its functions unavailable. As an Abyss Raider, you must survive, explore the underground world and find a way out.

Explore the Abyss

You fight unknown creatures while exploring the vast cave, searching for scattered relics and trying to uncover the secrets of the underworld. You can develop weapons, gear and Turret Units, and use different weapons and ammunition during your exploration.

Defend and gather

You design and build Turrets in real time to defend against continuous enemy attacks. A Robot Assistant helps you fight, collect resources and maintain the Turrets. Your Drilling Truck Survivor is designed for self-repair, ore extraction, production, and research and development, though its damaged state leaves many functions unusable.

Modular defenses

The Modular Automatic system lets you combine modules to build devices with different functions. A Battle Turret needs both weapons and ammunition boxes to operate.
