Lost Skies: Island Creator
SteamLost Skies: Island Creator allows you to create your very own island for the upcoming co-op survival game Lost Skies. Create your own sky island full of stunning vistas and brutal enemies, then release it into the world via the Steam Workshop!

Create Your Own Island
The Lost Skies: Island Creator is a free standalone tool where you can create the island of your dreams or your friend’s nightmares. Form the basic look of your island using simple geometric shapes, then sculpt away until you get your island looking exactly how you imagined it. Want a giant cave system or mountain range going through the island? You can do it!

Decorate Your Island
Create a beautiful island filled with lush forests and stunning vistas or an island full of mystery and danger littered with foreboding caves full of dense fog and dangerous ruins filled with enemies and traps. No matter what you choose, you will be able to bring your island to life!

Create Puzzles and Add Threats
Not every island is peaceful. Add dangerous threats such as enemy drones or create puzzles for players to solve to find treasure. How hostile (and rewarding) you make your island is up to you!

Share Your Island with the World!
After you’ve put the finishing touches on your island, upload it to the Steam Workshop for other players to explore! Change your mind? You can freely edit and re-upload your island as often as you’d like for everyone to enjoy!
