In the Pacific Ocean, three miles deep, lies a deep gorge known as the Half-Moon Trench. It is a place of literal darkness, unknown to most of the world. Now, it is home to an advanced deep-underwater mining facility known as the Scarlett Caldera. Owned by a powerful corporation, it operates with the goal of harvesting the secret to renewable energy.

But now, the Scarlett Caldera has inexplicably gone dark. Computer logs reveal the departure of escape pods, but none arise to the surface; grainy security footage shows staff members fleeing some unseen force within the facility; and all radio contact is gone.

Dispatched by G.O.R.E Sector, Raptor Pack sets out to investigate. Equipped with state-of-the-art exploration technology and combat weapons, Thomas Rodney and his team make the three-mile descent into the trench.

There, they find the station dark, vacant, and deathly quiet. Thin grooves line the bulkheads, bloodstains soak the decks, but no bodies are found. But something moves within the darkness.

Watching.

Waiting.

As the team presses further, they uncover the true purpose of the Scarlett Caldera’s operations, as well as the deadly consequences.

With disaster looming, Raptor Pack must race against time to rescue a small group of survivors and destroy all mutations inside Half-Moon Trench.
