Arena Online is an RvR (Realm vs Realm) MMORPG that features a daily battle for supremacy between three different factions. Guilds play an important part in the game as they can lay siege to and capture castles. Players can choose from one of the three factions of the Nordic Brotherhood, Elves, Forest Domain, and Humans, Justice Order, however, you will be at war with the other factions at all times. Players can personalize their character by improving skills rather than using a character-based model.
Arena Online was formerly published by Kalicanthus Entertainment, but for now, the game appears to lack a NA and EU publisher but is still available in Russia. Arena Online is free-to-play and offers a premium service and item mall.
