Gun Gale Online

«Gun Gale Online» (ガンゲイル・オンライン) is a VRMMOFPS, developed and operated by an American company called Zasker, that emphasizes on gun usage. It is the setting for the Phantom Bullet Arc (Volume 5 and 6). One of the main events in GGO is the multi-player versus player tournament known as the Bullet of Bullets (BoB).

System
Gun Gale Online was created with the help of the free VRMMO game development support package, called «The Seed», and utilizes FullDive technology to set players inside a post-apocalyptic world. It's thus part of the world seed so players from other games can be converted into GGO and GGO players can also have their character converted to other «The-Seed»-compatible games using this mechanism.

Setting
The game is set in a stage that players returned from space by space ships to a post-apocalyptic earth with all its civilization destructed by wars. The capital city of the game, SBC Gurokken, was originally a spaceship, with SBC meaning Space Battle Cruiser. There're city ruins exist below it.

Gameplay Basis
The basis of gameplay is on increasing levels which in turn increase stats which are increased based on player's choices. 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 long-term. Also, in place of guilds and parties it uses a squadron-type team play.

Stats

 * AGI (Agility) - determines movement speed of a character
 * VIT (Vitality) - determines health of a character
 * DEX (Dexterity) - determines accuracy of a player and ability to hit targets
 * STR (Strength) - determines the carrying capacity and ability to wield certain guns
 * DEF (Defense) - determines the defense of a player

Skills
As many other VRMMO, it also has a system of skills, most of them are related to the weapons the player use, while others are used to create weapons such as «knife creation» and «weapon creation» skills.

Currency
Credits is the form of currency of Gun Gale Online. The initial amount received at the start of the game is 1000 credits. GGO is the only VRMMO that allows you to trade the game's currency for real money. The convesion rate is 100 credits to 1 yen.

Weapons
There're mainly two types of guns in Gun Gale Online, with each of them have differentiated advantages and disadvantages that limited their use. Non-gun weapons like Kagemitsu G4 also exist in this game.
 * Optical guns - firing light-based ammunition, they are used primarily to hunt mobs. When used to against players. Their disadvantages include decreased effectiveness, lighter, longer range and smaller package size, but the fact that they can be negated with defensive equipments made it not suitable to be used against players. Optical guns are all given with virtual names and shapes.
 * Live-fire guns - meant for player to player battles as they are capable of ignoring most counters meant for optical weapons. It can pass through defensive field of equipments and able to deal higher damage per hit compare to Optical weapons. However its use is limited by its the fact that their magazine are very heavy and their trajectory is affected by wind and humidity. Guns in this category are all originated from guns existed in real world.

Log-out
Gun Gale Online utilizes the soul-less logout, like the system used in ALfheim Online, 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.

Servers
There are two separate servers for Gun Gale Online: the American and the Japanese servers. Until the aftermath of the first BoB, anyone from the American server could choose to play on the Japanese server and vice versa, though only a few players chose to play on a foreign server. This also meant that an American could participate in the Japanese version of the BoB. However, after the first BoB, the two servers were separated, meaning that American players could no longer connect to the Japanese server and vice versa, though an American player did somehow manage to get into the 4th BoB despite the regional block.

Others
To play Gun Gale Online, a player must pay a connection fee of 3000 yen every month. Players are given 6 months window time to pay the connection fee. If a player does not pay the connection fee within 6 months, the account of the player will be deleted.
