"Elteria Adventures is a creative online sandbox adventure. Build impressive architectural structures. Explore a vast, fantastic and beautiful world of skybound islands. Reshape or destroy anything you encounter. Play solo, or call over your friends. Adventures await!"

Featuring cross-platform online play, along with Linux support, there's no date set yet for when it will launch properly but this is the next major step for it. With a style that resembles a mix between Fortnite and Minecraft, I personally think this could end up finding quite an audience and they're being very careful to take their sweet time with it, to ensure when it does actually release that fun is the main factor.
