Xsyon

Xsyon is a unique apocalytic sandbox MMORPG that's an entirely player driven world that is constantly changing, based on player's actions and the environment's reactions. Players create their own realities as they form tribes, create quests, hunt, gather, form societies and develop a New World. Become a powerful warrior, a shrewd and savvy businessman, or a hardy farmer. Craft several different items, and learn new things to craft by doing so, all while the land changes based on actions players take, from terraforming, to city building.
