On April 26, two more infinitely scrolling Score Attack stages, "Orbit," and "Rage," will be available in a single 99-cent pack. Sometime in the future, the free DLC Pack #3 will include the "Chain Kill Mode," in which players attempt to kill as many enemies as possible while maintaining a combo. "A brand new world awaits if you are able to survive the attacking hordes!" If you're lucky, maybe it'll be a new horde-free world.
Like the "Chain Kill" DLC, the Xbox 360 version of Moon Diver remains undated, with Square Enix saying only that "Pricing and availability for the Xbox LIVE Arcade for Xbox 360 will be announced at a later date."
