Rakion is a third-person online shooter where you join rooms and play a set amount of rounds, like Gunz, but with medieval/fantasy characters, a special mode called "Golem Wars", the ability to level up, buy new equipment, and summon creatures. Team vs Team, Free For All, or solo/cooperative modes, Team vs Team can include Team Deathmatch or Golem Wars.

In Rakion, a player is a member of any of the five classes. The classes are Warrior, Archer, Blacksmith, Ninja, and Mage. Each class has a melee and a ranged attack. All characters can transform into "Chaos Mode", an ability gained by achieving a certain number of kills. You can also gain chaos points by losing games. Players who have the ability to transform into chaos mode have a blue glow surrounding their body as a warning to others. While in chaos mode, players have more vitality, cannot be knocked down, and deal increased damage.
