These stats determine how a character plays and operates in the game, the interval selection can not be altered later, so players must know how they wish to develop in the long-term.

Log-out

Gun Gale Online utilizes the soul-less logout, where the user can immediately log-out in safe zones, but in the field the body remains soul-less for a period of time and then the user is logged out. In the soul-less state, the user can be killed and have their items stolen, if their body is left unguarded.

Squadron

In place of guilds and parties, GGO uses a squadron-type team play. Some squadrons prefer hunting monsters, while others prefer battling against other players.

Weapons

There are mainly two types of guns in Gun Gale Online, with each of them have different advantages and disadvantages that limit their use.

Optical guns - firing light-based ammunition, they are used primarily to hunt mobs. Their advantages include being lighter, having longer effective range and precision as well as smaller magazine size than live ammunition guns do. However, defensive equipment can be used to disperse the damage of optical weapons, making them ineffective against players. Optical guns are all given fanciful names and shapes.
Live-ammunition guns - meant for player to player battles as they are capable of ignoring most counters meant for optical weapons. The bullets of such weapons can pass through defense fields and are able to deal higher damage per hit as compared to optical weapons. However, the disadvantages include having to carry extra heavy bullet magazines around and the fact that live bullet trajectory is affected by wind and humidity. Guns in this category are all originated from guns that exist in the real world.
Non-gun weapons, like swords or lightsabers, also exist in this game.
