About This Game

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.​​
