zOMG is a Gaia Online MMORPG game based in the world of Gaia. In this game objects have some how become animated and it's up to you and the rest of Gaia to help save Barton Town (and the other districts of Gaia) from The Animated. Obtain more rings (the weapons used by the players) by completing quests, or go to the Cash Shop or Nic's store and buy an array of different items to help you in your battles.
