ATMOSFAR Launches in Steam Early Access With a Fresh Take on Co-op Survival

Atmosfar is officially available in Steam Early Access, inviting players into a survival adventure that swaps oceans and forests for a world of floating islands.

Developed by Apog Labs and published by Shueisha Games, the game combines exploration, crafting, base building, and cooperative play in a sci-fi setting where nearly every journey begins in the air. Instead of traveling across land, you'll pilot personal aircraft to reach scattered islands while expanding a flying headquarters that serves as your mobile home. The game has reached 400,000 wishlists on Steam!

Survival Above the Clouds

Rather than placing players in another familiar survival sandbox, Atmosfar builds its identity around vertical exploration.

You'll travel using compact flying vehicles known as Wasps, gather resources across different biomes, and return them to the Cloud Cruiser, an airborne base that can be upgraded with new facilities and equipment as you progress.

The result is a gameplay loop that constantly encourages exploration instead of settling permanently in one location.

Players can experience the adventure alone or team up with up to four players in online co-op, making resource gathering, construction, and exploration a shared experience.

What Early Access Includes

According to the developers, the Early Access version introduces the core systems that define Atmosfar, including:

• Exploration across floating islands
• Flying vehicles for traversal
• The Cloud Cruiser mobile base
• Crafting and progression systems
• Solo gameplay
• Online co-op for up to four players

The studio also plans to continue expanding the game throughout Early Access with additional regions, gameplay systems, and story content shaped by community feedback.

Why Atmosfar Stands Out

Co-op survival games remain one of Steam's most competitive genres, but Atmosfar differentiates itself by making movement one of its biggest attractions.

Instead of crossing oceans or driving vehicles across massive landscapes, players spend much of their time navigating open skies, discovering floating islands, and continuously upgrading a headquarters that travels with them.

For fans of cooperative survival experiences looking for something beyond traditional base-building games, Atmosfar is one of the more distinctive Early Access launches to watch this season.
