Overview
Ubisoft Blue Byte is a German video-game development holding company within Ubisoft. It originated as Blue Byte, an independent studio founded in October 1988 in Mülheim by Thomas Hertzler and Lothar Schmitt, who had previously worked at the German publisher and developer Rainbow Arts. The company began with limited resources, reportedly operating from an attic office funded by a loan from Hertzler's parents, but soon established itself in European computer gaming. Its first published title was the tennis simulation Great Courts, released in 1989 by Ubi Soft, the French company that later became Ubisoft. Blue Byte's first major commercial success was Battle Isle, a turn-based strategy game released in 1991. The title developed a strong following in Germany and other European markets and led to expansions and sequels, including History Line: 1914-1918 and Battle Isle 2220. The studio broadened its portfolio with titles such as Albion, Chewy: Escape from F5 and Incubation. Its international expansion was difficult, however. Attempts to establish a stronger presence in the United States involved publishing relationships with Accolade and offices first in Chicago and later Austin, but the company remained more influential in Germany and continental Europe than in North America. Blue Byte's defining franchise emerged in 1993 with Die Siedler, marketed internationally as The Settlers. The management and settlement-building game became the company's best-known property and produced numerous sequels, expansions and later reinterpretations. The studio subsequently became associated with another major strategy franchise, Anno, through its work with Related Designs and later through direct development under the Ubisoft structure. Both series helped define Blue Byte's identity around strategic planning, simulation, economic systems and the construction or management of complex fictional societies. Ubisoft acquired Blue Byte in February 2001. At the time, the German company had 64 employees and activities in Germany, the United Kingdom and the United States. After the acquisition, Ubisoft directed Blue Byte toward its established strengths, particularly The Settlers and Anno, while also using the German organization on wider Ubisoft projects. Related Designs, a Mainz-based developer that had collaborated with Blue Byte and was acquired by Ubisoft in 2013, was merged into Blue Byte in 2014. This created a second major internal development location alongside Düsseldorf. The organization expanded again with the establishment of a Berlin studio. Announced in 2017 and opened operationally in 2018, Ubisoft Berlin became the third German studio associated with the Blue Byte legal structure. In 2017, the former Blue Byte brand was renamed Ubisoft Blue Byte. In 2019, the operating studios were presented publicly as Ubisoft Düsseldorf, Ubisoft Mainz and Ubisoft Berlin, while Ubisoft Blue Byte continued as their legal parent organization. The change was intended in part to give the individual studios a clearer Ubisoft identity and support recruitment and growth. The studios have contributed to projects including The Settlers: Kingdoms of Anteria, later reworked and released as Champions of Anteria, Anno 2205, Anno 1800, The Settlers and other Ubisoft productions. Their wider collaboration portfolio has included work connected with Might & Magic Heroes Online, For Honor, Tom Clancy's Rainbow Six Siege, Skull & Bones and Beyond Good and Evil 2. By August 2024, the three German studios together were reported to employ 695 people. Although the Blue Byte name has largely receded from public-facing studio branding since 2019, Ubisoft Blue Byte remains the legal umbrella for Ubisoft's Düsseldorf, Mainz and Berlin development operations.
History
Blue Byte was founded in October 1988 by Thomas Hertzler and Lothar Schmitt after the two left Rainbow Arts. The company's earliest operations were modest: its founders established an office in the attic of Hertzler's home in Mülheim using starting capital borrowed from his parents. Blue Byte's first published game was Great Courts, a tennis simulation released in 1989 by Ubi Soft. The relationship with Ubi Soft was significant because that publisher later became Ubisoft, the company's eventual owner. The studio gained wider recognition with Battle Isle, a turn-based strategy game released in 1991. Inspired in part by Japanese computer strategy design, Battle Isle developed a loyal audience and generated expansions and sequels. Blue Byte followed it with History Line: 1914-1918 and other projects, building a reputation for detailed tactical and strategic gameplay. In 1993, the company released Die Siedler, known internationally as The Settlers. Its combination of settlement construction, resource management, logistics and economic simulation became Blue Byte's signature achievement. The franchise continued through multiple installments and remained central to the company's identity. During the mid-1990s, Blue Byte produced or published a variety of additional games, including Albion and Chewy: Escape from F5. Most did not match the international impact of The Settlers or Battle Isle. The company also attempted to expand in the United States. A North American operation was established in Chicago in the 1990s and later moved to Austin, Texas. Although Battle Isle 2220 achieved some recognition in the United States, Blue Byte's strongest market position remained in Germany and other European territories. Changes to Battle Isle's formula also created difficulties: Incubation, released in 1997, moved toward three-dimensional tactical combat, while later experiments departed from the traditional turn-based format that many series fans expected. Ubisoft acquired Blue Byte in February 2001. The company entered the acquisition with 64 employees and a presence in Germany, the United Kingdom and the United States. Under Ubisoft ownership, Blue Byte concentrated on its strongest franchises while contributing to the wider publisher's production network. The German organization subsequently became involved in both internally led projects and support work for other Ubisoft properties. A major structural change occurred through Related Designs, the Mainz developer associated with the Anno franchise. Ubisoft acquired Related Designs in April 2013 after the two companies had collaborated on projects including Might & Magic Heroes Online. Related Designs was merged into Blue Byte in June 2014, creating a second internal studio. Work from the German teams during this period included The Settlers: Kingdoms of Anteria, Anno 2205 and Champions of Anteria. Champions of Anteria replaced the original Settlers branding and adopted a different gameplay approach. Blue Byte's organization expanded further when Ubisoft announced a Berlin studio in 2017. The studio occupied a building formerly used by Berliner Bank, began operating in early 2018 and held its official opening on 25 September 2018. It joined the Düsseldorf and Mainz locations as part of the German development network. In the same period, Blue Byte adopted the Ubisoft Blue Byte name and a revised visual identity. At Gamescom in August 2019, Ubisoft introduced a new corporate identity for its German operations. The public-facing studios became Ubisoft Düsseldorf, Ubisoft Mainz and Ubisoft Berlin, while Ubisoft Blue Byte remained the legal parent company. The reorganization was intended to strengthen recruitment and present the studios as integrated Ubisoft locations. The Blue Byte branding was subsequently reduced in public use, and its social-media presence was largely deactivated by December 2020. Nevertheless, the legal organization continued to oversee the three German studios. The German teams have worked on Anno 1800, The Settlers and a range of Ubisoft projects, including For Honor, Rainbow Six Siege, Skull & Bones and Beyond Good and Evil 2. As of August 2024, the three studios together were reported to have 695 employees. Blue Byte therefore functions less as a single consumer-facing studio than as the legal and historical umbrella for Ubisoft's German development operations, with its legacy most strongly reflected in The Settlers, Battle Isle and Anno.

Products and positioning
A German Ubisoft development organization focused on strategy, simulation, city-building and broader AAA game-production support.
City-building and economic strategy · 1993
The Settlers series
The Settlers is Blue Byte's most recognizable franchise. Beginning with Die Siedler in 1993, the series combines settlement construction, production chains, logistics, resource management and economic development. Its accessible presentation is paired with systems-heavy simulation, making it a defining example of European city-building strategy. Later entries experimented with different structures and combat systems, including the project that became Champions of Anteria and the later game titled The Settlers.
City-building and economic simulation
Anno series
The Anno series focuses on settlement growth, trade, production networks, exploration and the management of increasingly complex societies. Blue Byte's involvement was strengthened through its work with Related Designs and the integration of that studio into the German organization. Anno 2205 and Anno 1800 are among the projects associated with the Ubisoft-era German teams.
Turn-based strategy · 1991
Battle Isle series
Battle Isle was Blue Byte's breakthrough strategy property, beginning in 1991. The series emphasized turn-based tactical planning and generated expansions and sequels, including Battle Isle 2220. Later experiments such as Incubation and Battle Isle: The Andosia War altered the formula and divided some of the established audience, but the franchise remains an important part of Blue Byte's early history.
Sports simulation · 1989
Great Courts
Great Courts was a tennis simulation and Blue Byte's first published game. It was released in 1989 by Ubi Soft and represents the company's early work before its strategy franchises became central to its identity.
Role-playing game
Albion
Albion was one of Blue Byte's notable projects from the 1990s. Although it did not achieve the international impact of The Settlers or Battle Isle, it demonstrates the broader range of genres the company explored during its independent period.
