Players control a character in a three-dimensional plane but the scope of movement is mainly focused on the horizontal axis with limited vertical movement, much like the arcade style side-scrolling classics. In its current state, players can progress through 65 levels in the North American release with the level cap reaching as high as 80 on servers in Asia.
Combat is action-based with moves performed in real-time. All combat is centered around the use of special skill sets on cool downs. Players can also perform ground and aerial combos by utilizing certain skills in order to render enemies unable to retaliate but can also play the role of a healer or supporter when necessary.
There are also a large number of missions and scenarios for a player to complete co-operatively with others. Each individual dungeon has one to four separate modes for advancement, each increasing in difficulty and not being accessible until the previous instance has been cleared. At the end of every mission sequence is a scenario that advances your character to the next stage of the game.
