"Fantasy Earth Zero" is a massive multiplayer online role-playing game (MMORPG) in which the player controls a customisable avatar and chooses one of the five nations to ally with and fight for. There is no storyline, with the intended narrative being created by the battles of player factions. In the game's setting of Melpharia, a long era of peace causes ancient petty differences between the nations to erupt into full-scale wars for control over magical crystals that gave birth to all things. During the character creation stage, the player chooses a gender, character class, weapon type and starting nation. The main emphasis of gameplay is player versus player (PVP) battles, carried out on the same server; starting with a minimum of seven versus seven, it goes up to large-scale battles between two armies of fifty players. Alongside this, there is a player versus environment element, with players able to fight hoards of monsters for lower rewards.
