Guild Wars is a a massively multi-player online role-playing game (MMORPG) with an emphasis on tactical combat. In single player, multiplayer and guild-based missions, players will explore a fantasy world while pursuing professions and gaining skills that help them develop and advance their unique character. It provides two main modes of gameplay—a cooperative role-playing component and a competitive PvP component—both of which are hosted on ArenaNet's servers. Players can group with other players and non-player characters, known as henchmen and heroes, to perform missions and quests found throughout the game-world. PvP combat is consensual, team based, and limited to areas designed for such combat. Players are allowed to create characters at maximum level and with the best equipment specifically for PvP play, which is unusual for MMORPGs.
