ATMOSFAR regions are groups of floating islands at different heights above the clouds of Tycos. The October 2026 Early Access build contains two of the three planned major regions, with their islands, biomes and story content ready to explore. The final region, The Rime, will arrive later.
You begin in Caligo Cays, the lowest region, where lush islands and frequent moisture make the landscape relatively green. Further travel means reaching higher altitudes, dealing with different weather and terrain, and upgrading your flying capabilities rather than using the first Utility Wasp for every journey.
ATMOSFAR regions available in Early Access
The two launch regions contain their main islands, smaller islets and story objectives. You can continue across those areas as the plot unfolds and use the Wasps and Cloud Cruiser to support increasingly long trips. You do not need a later content update to visit the islands that already belong to the two launch regions.
The third area is The Rime, the planned final region. It forms part of a future update along with the Scout Wasp and final story chapter. Players in the current release should concentrate on exploring the available two-region map and improving their fleet, rather than searching for an entrance to a region that is not part of the October build.
ATMOSFAR regions: exploring Caligo Cays
Caligo Cays lies at the lowest altitude and features rich vegetation, rain and moisture. Pearl Island is part of the early experience, where you learn aircraft repairs, gathering and flying before moving into wider exploration. PACE buildings and abandoned facilities contain clues about the outpost whose disappearance drives the story.
Altitude changes the environment as you explore Tycos. Islands at different heights can have distinct plants, animals and weather patterns. Use the local resources for crafting and fuel, and keep an eye out for landmarks that will help you return to your aircraft after a longer journey on foot.
ATMOSFAR regions: reaching higher islands
The Utility Wasp is built for flexible shorter expeditions. As you progress, other aircraft and upgrades provide different performance and capabilities. Keep the engine and hover equipment in good condition, upgrade components when the game allows, and prepare enough hydrogen before trying to reach a distant island at a different height.
Travelling between ATMOSFAR regions places greater demands on your aircraft and supplies. Follow the main objectives while upgrading equipment and preparing for the next stretch of the journey. The Cloud Cruiser is useful for moving supplies and Wasps towards new destinations rather than repeatedly starting every expedition back at Caligo Cays.
What resources to look for while exploring
Different ATMOSFAR regions contain scrap, minerals, plants, organic materials and artifacts to collect. Some artifacts can be researched at a camp desk to unlock useful crafting knowledge. Hydrogen crystals are especially valuable near geysers because they can be refined into liquid fuel for Wasps and the Cloud Cruiser.
For each new island, check your objective, identify a landing area and make sure you’ll have enough fuel to return to camp or your airship. A Hauler Wasp is useful when a site contains bulky scrap; a Utility Wasp lets you establish a portable workshop; a Striker gives you a faster armed option.
When does The Rime open?
The Rime will be the last of the three ATMOSFAR regions, arriving in a later update with new islands, a new biome and the Scout Wasp. Apog Labs has described the Scout as an exceptionally fast exploration class with resource and hazard scanning abilities. It is part of the roadmap, not one of the current three available vehicles.
Explore Caligo Cays and the rest of the two-region Early Access world, finish the available story objectives and improve your fleet for longer journeys. The future Rime update will expand that route into the final region while giving players another aircraft designed for exploration.
