Mirage Arena *Game Field*

In the Mirage Arena, a gameplay mode for up to three players known as Joint Struggle is held. Here, players can interact in the Lobby and later battle the Unversed cooperatively. Joint Struggle features unique abilities that cannot be used in other types of gameplay, and allows bonuses to be obtained for the game's single-player story mode.
Upon entering the area, the players can choose whether to play in an online or offline lobby. Once there, the player has access to several events. From its exterior appearance, the Mirage Arena appears similar to Space Paranoids. A central orb in the middle, several protrusions and large, strap-like objects surround it.
On the inside , the world has an appearance similar to a space station. In the Lobby, glowing neon steps highlight a dark floor. A wide window gives a view of space, and a Moogle stands in the corner running the Medal Shop. When you set records in the Arena's games, you can get medals and exchange them for rare items in the shop. Blue data screens are also displayed on the window. In the Battle Arena, red screens surround the players as they battle Unversed on a terrain colored varying shades of blue. The surrounding space can also be seen through the windows in this area. A third area, also used for battle, places players in a room with a dark floor and walls.
The arena actually transports the players to different areas of other worlds, such as the play area in Land of Departure.
