Outwar, Rampid Gaming's browser-based sci-fi MMORPG is a text-based entry into the 2-D multiplayer offerings out there. Traditional methods of advancement like monster hunting, quests, and grinding ate all in here. But the game has unusual classes - monster, pop star, and gangster, over 60 quests, and a full-featured PvP system.
The PvP mechanics include both solo and guild-wide battles, in addition to a bounty hunting system. PvP will strip the losing player of XP. Desipte the graphical limitations, Outwar will provide challenge for those who want it. It's free to play, but paid upgrades are available. Outwar has seen several expansions and continues to be updated.
