Scavenger

In Scavenger, the surface of the world was covered by a toxic atmosphere over a hundred years ago. As a result, the remaining people lived above it, on top of the remnants of the old civilization. They built settlements on mountain peaks and rooftops. However, most of these settlements have now been abandoned.

You are a young survivor who fights for survival alone above the sea of toxic clouds. You fly around with your self-built airship, searching for the last places above the toxic clouds for food and scrap materials to craft with.
