The Old World is Gone. Can You Build a New One?
The Swarm consumed civilization. Now, survivors cling to life in rusted strongholds. But you—guided by a forgotten starship—dive into the ruins, leading a squad to scavenge, fight, and uncover the truth.
Scavenge or Die
The fog hides monsters... and miracles. Lost technology waits in the wreckage—use it to tip the scales.
Adapt or Be Overrun
Enemies strike without warning. No static defenses—push forward, fall back, outmaneuver. Every map is a new nightmare.
Jury-Rigged Warfare
Turrets are ammo, not assets. Drag them, break them, modify them. Your only rule: survive.
War Machine
You’re not just a soldier—you’re an engineer, a strategist, a leader. Research, craft, and turn scraps into salvation.
