Aeria Games & Entertainment has announced the start of the open beta test for Cronous, a classic, fully-featured MMORPG that's free to play on AeriaGames.com. Cronous features four unique character classes, fully customized appearance based on equipped gear, an advanced combat system combining magic spells and medieval weaponry, as well as hundreds of maps, dungeon levels, and quests. You can form guilds to play cooperatively with other players, raise pets, craft weapons, or go on large-scale castle sieges. To celebrate the launch of open beta, Aeria Games announced they will award a Nintendo DS Lite to one lucky player of Cronous. To apply for the open beta, register an account here.
