Survive the Skies in Altitude Zero

Altitude Zero is an intense atmospheric horror survival game that traps you in a claustrophobic, high-stakes fight for your life. As the pilot of a fragile hot air balloon, you must navigate through desolate, ghost-filled canyons. Your objective is simple yet deadly: traverse the treacherous terrain to locate and deactivate mysterious extraction stations that have unleashed an ancient, cosmic evil upon a shattered Earth.

Every moment in this indie horror experience is a battle against the elements and your own sanity. With only a paper map for navigation and the flickering light of your burner to push back the encroaching shadows, you must master balloon flight mechanics while avoiding lethal winds and aggressive, otherworldly entities. The survival horror elements demand nerves of steel as you balance the need for altitude, fuel management, and the terrifying reality of landing to perform maintenance on the ground.

Key Gameplay Features

• Ground-Based Operations: Take calculated risks by landing your ship to refuel or sabotage deep-sea extraction stations, but be quick—you are never safe once you leave the air.
• Analog Navigation: Abandon modern tech for a tactile experience; rely solely on an old-fashioned paper map to plot your course through the labyrinthine ruins.

The Story of a Dying World

Following a cosmic cataclysm that left Earth a barren, ghostly wasteland, the atmosphere is choked by violent storms and the oceans have mutated into thick, crimson fluid. A scientific expedition attempted to siphon this substance using vast drainage stations, but their intrusion into the seabed awakened a dormant, primordial horror. Now, the situation is spiraling into absolute chaos. You are the last hope in this post-apocalyptic survival horror thriller—brave the canyons, silence the stations, and hold back the total destruction of what remains of humanity.
