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.

Compose a team of superheroes, each with their own playstyles, backstories, and grudges. Pit them against a variety of maniacal and formidable villains. Defeat your enemies and save the Multiverse! The rules of the game are deceptively simple: Play a Card, Use a Power, and Draw a Card. What makes Sentinels of the Multiverse unique is that each card has special abilities that can create powerful combos or even change the rules of the game!
