Twin Harbour Interactive

Twin Harbour Interactive is an international developer and publisher of free-to-play, cross-platform long-term strategy games. Formed in April 2025, it brings together the strategy-game operations previously associated with Hamburg-based Bytro Labs and Malta-based Dorado Games under the Supremacy franchise.

The studio builds persistent multiplayer campaigns in which players manage diplomacy, economies and military strategy over days, weeks and months. Its games span browser, PC, Steam, iOS and Android, combining grand-strategy systems with live operations, multiplayer infrastructure and in-game economy design.

Supremacy franchise

Twin Harbour Interactive’s portfolio includes:

• Supremacy: 1914, a World War I-themed persistent grand-strategy game
• Supremacy: Call of War 1942, a World War II real-time global military strategy game
• Supremacy: World War 3, a modern geopolitical warfare strategy title
• Iron Order 1919, a dieselpunk alternate-history strategy MMO
• Supremacy: Warhammer 40,000, an upcoming licensed grand-strategy title developed in partnership with Games Workshop

Its dual-hub development model divides franchise work across Germany and Malta. The Hamburg team focuses on historical strategy titles including Supremacy: 1914, Supremacy: Call of War 1942 and Iron Order 1919, while the Malta team leads Supremacy: World War 3 and new franchise production.

Development and publishing

The company provides full-cycle game development, publishing, live game operations, systems and network engineering, multi-platform porting, user acquisition, community management and player support. Its strategy focus is supported by a flexible hybrid working framework and a team of more than 150 developers, artists, QA leads and live-operations specialists representing more than 30 nationalities.

Twin Harbour Interactive is part of Stillfront Group and operates the Supremacy franchise through two underlying Stillfront Supremacy legal entities in Germany and Malta.
