An environmental catastrophe has poisoned the surface with toxic miasma. Staying on the ground will lead to suffocation and sickness.
As a survivor, you must climb upward using giant forest trees, elevated walkways, and other structures. Secure safe zones high above, build your home, grow crops, and raise creatures to survive long-term.
"Here, falling is not failure — giving up is."
"Below is hell, above is heaven — and you hang between life and death."
Your journey begins in a silent, dead forest. Gather rusted steel bars and scrap materials to build your first simple camp.
Foundations of Survival — Build basic campfires, crafting stations, and rain collectors. Remember: you need a safe shelter as soon as possible.
Vertical Expansion — Use the frames of ruined buildings to construct spiral staircases and suspended walkways. You will no longer expand horizontally, but build upward layer by layer.
Sky City — When your structures break through the clouds, a whole new world unlocks. Build floating farms and shelters among the clouds to create your own self-sufficient sky settlement.
Survival Management: Monitor your hunger, thirst, stamina, and miasma poisoning. Stay alive by farming, raising animals, and scavenging supplies.
Environmental Effects: Strong winds, thick fog, and heavy rain make climbing harder. Spreading miasma threatens high-altitude safety, crops, and livestock.
The ground is too contaminated for crops to grow. Keep climbing upward to collect all available seeds and resources.
Vertical Farming — Plan your aerial garden on balconies, rooftops, or dedicated growing racks.
Crops — Find seeds from the old world and grow hardy plants adapted to extreme high-altitude conditions. Some provide more energy, while others can be used to make medicine.
Secrets of the Vertical World — Every height holds unique supplies, building blueprints, and the truth behind the fall of civilization.
Layered Dangers — feral scavengers, extreme cold and thin air at high altitudes, and threats from unknown flying objects are all challenges you must face.
