The wait is almost over. Lost Skies, the highly anticipated co-op survival adventure from Bossa Games, is officially leaving Early Access and launching into its full 1.0 release on September 17, 2025, exclusively on PC via Steam. After months of community-driven updates, bug fixes, and fresh content, players are about to experience the most complete and ambitious version of this skyfaring journey yet.
A World Above the Clouds
In Lost Skies, the sky isn’t just the limit—it’s your playground. Players can team up with up to five friends to explore a breathtaking, shattered world suspended above the clouds. Ancient ruins and forgotten technologies await discovery, while colossal sky-beasts known as the Seraph challenge your survival skills.
At the core of the game lies the customizable skyship, a floating fortress that acts as both your home and your weapon. Every ship is upgradeable and designed from scratch, allowing players to personalize their aerial base before taking on towering bosses or gliding across uncharted skies with grappling hooks, wingsuits, and gliders.
A Spiritual Successor to Worlds Adrift
Longtime fans of Bossa Games will recognize the DNA of Lost Skies. The studio’s 2017 sandbox MMO, Worlds Adrift, became a cult classic for its ambitious exploration and ship-building systems, though it never reached full release. Now, with Lost Skies, Bossa has revived and refined the vision, crafting a true spiritual successor.
Lead Game Designer Luke Williams reflected on the journey:
“Lost Skies was such a unique opportunity for a designer. We wanted to elevate what players loved from Worlds Adrift—like exploring floating islands and building unique skyships—while pushing the experience even further. Over the past three years, we’ve worked hand-in-hand with our community to create something lasting, something players can enjoy for years to come.”
What’s New in 1.0
Bossa’s signature creativity and physics-driven gameplay shine brighter than ever in Lost Skies. Here’s what players can look forward to in the full release:
- Island Creator – Players can design and share their own floating islands, adding endless variety to the world. Many of these fan-made creations are already part of the game.
- Limitless Skyships – Build and customize your vessel piece by piece, crafting the perfect base to match your style.
- Expanded Gameplay – New weapons, ship assets, naval boss battles, regions, puzzles, and improved inventory systems have all been added since Early Access.
- Full Keybinding Support – Play your way with complete control customization.
- Polish & Performance – From bug fixes to stability upgrades, the game has been fine-tuned for a smooth, immersive experience.
From Surgeon Simulator to the Skies
Bossa Games may be best known for its quirky physics titles like Surgeon Simulator and I Am Fish, but with Lost Skies, the studio is proving it can blend humor, innovation, and depth into an epic adventure. Community testers have already praised the grappling hook system as one of the best ever implemented, rivaling mechanics from big-budget AAA games.
