Ragnarok Odyssey Ace is a completely evolved version of the popular giant-hunting game released on PlayStation Vita, adding a wealth of new content and features and introducing a PlayStation 3 version. New job-specific Ace skills change the battle dynamic significantly, while the addition of hirable in-game mercenaries ensures that players can have a battle party to take on the toughest foes even when they can't get online. The new Yggdrasil Tower, with its randomly generated levels, along with a consistent supply of new online quests, ensures that there will always be unique content each time the game is played.
