Check it out on Steam. That's where I saw it.
Xsyon is a player driven apocalyptic fantasy sandbox MMORPG, set in a living and evolving environment. Players create the world they want to live in as they form tribes, construct towns, shape landscapes, create quests, hunt, farm, gather, build societies and develop a New World.
Pictures on the steam suggest Rust + Archeage or something in that vein
