Mythic's Ultima Forever: Quest for the Avatar is out for the iOS and can be played on the iPad 2, iPod 5, and iPhone 4S or higher.
Mythic had recently held Ultima Forever back to fiddle with its economy and fix bugs, but it seems as though everything is solid enough for the studio to finally pull the trigger and launch it worldwide.
Ultima Forever is free-to-play with optional in-app purchases. Mythic is working on Android and PC versions as well. It's a whopping 881 MB to install, so make sure you have the room before you check out this latest chapter in the Ultima series!
