Overview

About this game

Prepare for a hardcore military sci-fi survival roguelike. Earth has been scarred by endless warfare, corrupted by the Modification Drones, an ancient combat augmentation, leaving the environment mutated and hostile.

Cmd. Larson: "The might of the Earth Military will pierce through the corruption!"

As veteran Kuno Lee’Larson, you crash-land into the dangerous Brianna Wilderness and must save the local sector from their impending doom! Fight against the onslaught of monsters, defend allied infrastructure, and get to know the many characters and their unique stories in this world.

Explore the sector and find valuable loot in long-forgotten places. The world around you is harsh, and you must adapt if you want to survive. Your allies will help where they can, but they won’t hold out forever.

Brianna Corps Soldier: "FOR THE BRIANNA CORPS!"

You must rely on food, medicine, and the nearby artillery to keep enemies at bay. This requires a great deal of resources, and you must ensure your industry keeps producing supplies. You then transport these via military truck to the artillery for the production of shells.

Prepare yourself solider, the wilderness awaits you!
