Last updated August 24, 2026
Overview
Blueside is a South Korean video game publisher and game-industry company. Public reference material identifies it primarily through its relationship with Phantagram, a South Korean development studio known for the Kingdom Under Fire series. Blueside acquired Phantagram in 2010, bringing the studio and its established intellectual property into the same corporate structure. The acquisition connected Blueside with a franchise that had originated with Kingdom Under Fire: War of Heroes and later expanded to console titles including Kingdom Under Fire: The Crusaders and Kingdom Under Fire: Heroes. The available material does not provide a verified founding year, founder, headquarters address, ownership structure, financial information, executive roster, or detailed account of Blueside's current operating status. It also does not establish a complete chronology of games directly developed or published by Blueside itself. Accordingly, the company is best described conservatively as a South Korean game publisher associated with a development and intellectual-property portfolio inherited or consolidated through Phantagram. Phantagram's history provides important context for Blueside's position in the Korean games sector. Phantagram was founded in 1994 by a group of teenage students and began developing games during the late 1990s, including titles for the MSX computer. It became one of the early generations of Korean game developers. In 2000, under a new slogan, it released Kingdom Under Fire: War of Heroes, a fantasy strategy game that achieved success in Korea and internationally. The series subsequently expanded across PC and Xbox platforms. The broader portfolio associated with Phantagram includes Kingdom Under Fire: A War of Heroes, Blade Warrior, Forgotten Saga, Zyclunt, Shining Lore Online, Kingdom Under Fire: The Crusaders, Kingdom Under Fire: Heroes, Phantom Crash, and Ninety-Nine Nights. Phantagram developed or co-developed several of these games, while Phantom Crash was published by Phantagram and developed by Genki, and Ninety-Nine Nights was co-developed with Q Entertainment for Xbox 360. These credits should not automatically be treated as games developed by Blueside, but they explain why Blueside is linked to a recognizable international console and PC-game catalog. No reliable source in the supplied material confirms a current flagship release, a current executive team, a publicly traded status, or a current market strategy. The official website is retained as the principal company URL, while the available encyclopedia reference is used for the documented Phantagram relationship and associated game history.
History
Blueside's documented history in the supplied reference material is centered on its 2010 acquisition of Phantagram. The available sources do not state when Blueside was founded, identify its founder, or provide a detailed account of its corporate development before or after the transaction. They also do not establish a verified current headquarters, ownership structure, public listing, or active product pipeline. The Phantagram acquisition is significant because Phantagram was an early South Korean game-development studio with a substantial history of its own. It was founded in 1994 by teenage students and began producing games from 1997, with early work including titles for the MSX computer. During the 1990s it was part of the first generation of Korean game developers. In 2000, Phantagram released Kingdom Under Fire: War of Heroes under a new corporate slogan. The game achieved success in Korea and overseas and became the foundation of a broader franchise. Phantagram's later catalog covered both computer and console platforms. Its listed PC projects included Kingdom Under Fire: A War of Heroes, Blade Warrior, Forgotten Saga, Zyclunt, and Shining Lore Online. On Xbox, the studio was associated with Kingdom Under Fire: The Crusaders, Kingdom Under Fire: Heroes, and Phantom Crash. On Xbox 360, it co-developed Ninety-Nine Nights with Q Entertainment. The latter was a fantasy and strategy action game, while Phantom Crash was published by Phantagram and developed by Genki. These distinctions matter because they describe Phantagram's development and publishing relationships rather than proving that every title was directly made by Blueside. When Blueside acquired Phantagram in 2010, it gained an association with the Kingdom Under Fire property and with a studio that had experience across PC, Xbox, and Xbox 360 markets. This transaction is the clearest documented turning point connecting the Blueside name to the international console-game business. Beyond that relationship, the supplied materials do not provide enough verified information to construct a complete corporate chronology or to determine whether Blueside currently operates as an active publisher, developer, holding company, or another form of games business. The company should therefore be documented as a South Korean game publisher associated with Phantagram and its catalog, with further corporate details left unconfirmed.

The Kingdom Under Fire franchise is the principal game property associated with Blueside through its acquisition of Phantagram. It began with Kingdom Under Fire: War of Heroes, a fantasy strategy title released in 2000, and later expanded to console entries including Kingdom Under Fire: The Crusaders and Kingdom Under Fire: Heroes. The series is associated with a blend of fantasy warfare, strategic command, and action-oriented gameplay.

Phantagram catalogVideo game portfolio
The catalog associated with Phantagram includes PC titles such as Blade Warrior, Forgotten Saga, Zyclunt, and Shining Lore Online, as well as console-related projects including Phantom Crash and Ninety-Nine Nights. The portfolio reflects Phantagram's role as both a developer and publisher, with some projects involving outside partners. Because Blueside's acquisition took place in 2010, these games are best treated as associated catalog assets and historical context rather than as uniformly Blueside-developed products.
