Welcome To Gun Gale Online!

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

The game started operation in April 2025 and has become the most famous Sci-fi VRMMO game in the Sword Art Online Universe since then.


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 is thus part of «The Seed Nexus», allowing players from other games that are part of the nexus to convert their avatars in the game into GGO and vice versa, though at the cost of not being able to transfer items, having the avatar's stats adjusted to maintain the relative strength between the two games and the player not being able to use the same avatar in the previous game unless it is converted back again.


The game is set in a post-apocalyptic Earth, which had become a wasteland after a huge war long ago, that people had returned to on space ships. The capital city of the game, called SBC Glocken, with SBC meaning Space Battle Cruiser, was originally the spaceship that was used to return to this planet. A huge city of ruins from the war, which has an unlimited number of automated fighting machines and mutant creatures that await adventurers, sleeps beneath the capital city.


The basis of the game's gameplay is to increase one's level, which in turn increases stats that 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 the long-term.
