The developers of Sphere 3 have announced that a new expansion is coming soon. Called Rage of the Devastator, developers have said, "Forget everything you knew -- it's time to see Sphere 3 in a new light!" The update will bring enhanced graphics, a rebalanced combat system, a brand new "weapon speed mechanic", changes to the equipment system, a new zone, quests and an increased level cap to 60.
Over the coming weeks, developers plan to release more specific information about Rise of the Devastator and provide information about how players can get involved in an open beta of the new content via the public test server.
