Atlantica Online is a free-to-play, massively multiplayer online role-playing game (MMORPG). Published by NDOORS Corporation, the game was launched in October 2008. It has a fantasy setting blended with some technological elements.
Unlike many MMORPGs, Atlantica Online features turn-based combat, along with a mercenary system that lets players bring multiple mercenaries on the battlefield with them, according to their needs. The game has nine player "classes," based on the weapon used, as well as over a dozen different types of mercenaries that may be recruited. The game supports both player versus environment (PvE) as well as player versus player (PvP); the latter is supported by a territory and guild system.
Atlantica Online has received several awards for its innovative gameplay in the free-to-play industry.
