In Devast.io, you are in a post-apocalyptic world where nature takes back its rights. You must build a bunker, weapons, warm up and produce your own food to protect yourself from this ruthless world and the many other survivors. The biggest thing that makes devast different from other survival games like starve.io is that there is radiation in devast. Use the arrow keys or WASD to move. Left click to hit. Shift to speed up. E to interact. C to craft and skill, and M for the map.
