Sea Warden Demo Now Available!
Alcedo Games
Hello everyone!
We’re excited to introduce the demo of our brand-new co-op survival game: Sea Warden Demo !
https://store.steampowered.com/app/4832320/Sea_Warden_Demo/
The game takes place on a magical living island carried on the back of a massive sea turtle named Ao, drifting with you across the endless ocean.
In Sea Warden, you will:
Survive together with your closest friends and explore a mysterious island surrounded by the unknown. Chop trees, mine resources, scavenge materials, and build a cozy camp strong enough to withstand violent storms. When sea monsters rise from the darkness, fight side by side with your companions to defend your home!
In your quiet daily life with Ao, you will feed and care for your giant turtle companion, protect the living island you depend on, collect lost animal spirits, and enshrine them in the Totem Temple. Together, you will transform your island into a lively moving sanctuary on the sea.
If Sea Warden has caught your interest, please consider adding it to your Steam wishlist! Your support gives our team tremendous encouragement and motivation to keep moving forward.
