Firefly Studios

Firefly Studios is a UK video game developer and publisher focused on strategy games that combine real-time tactical battles with medieval castle construction, economic management, and city-building systems. Founded in 1999 by former Impressions Games designers and programmers Simon Bradbury and Eric Ouellette, the studio is best known for the long-running Stronghold franchise.

The original Stronghold launched in 2001, establishing Firefly’s blend of castle simulation and real-time strategy. The studio expanded the series with titles including Stronghold: Crusader, Stronghold 2, Stronghold Legends, Stronghold 3, Stronghold Crusader 2, Stronghold: Warlords, and modern Definitive Edition releases. Its wider catalogue also includes the science-fiction management game Space Colony, the historical city builder CivCity: Rome, and the online strategy title Stronghold Kingdoms.

Strategy development and live games

Firefly develops games for PC and mobile platforms, with capabilities spanning:

• Real-time strategy, tactical battle simulation, and historical scenario design
• Castle building, defense, economic simulation, and city-building mechanics
• Full-cycle game design, programming, writing, audio, visual production, QA, and localization management
• Remastering, porting, Definitive Edition overhauls, and long-term community support
• Live-service operations for MMORTS games, including server hosting, balancing, player support, and community management

The studio has worked with isometric 2D strategy technology as well as Unreal Engine 5 for newer development. Stronghold Kingdoms entered open beta in 2010 before launching on Steam in 2012 and mobile in 2017, extending Firefly’s strategy design into persistent online play.

Firefly Studios became an active operating subsidiary of Devolver Digital, Inc. in November 2021. It continues to develop its own strategy projects, including Stronghold 4, while maintaining and expanding the Stronghold catalogue.
