astragon Development

astragon Development is a game development studio based in Hamm, Germany. Founded in 1990 as Independent Arts Software, it develops, co-produces and adapts commercial games across PC, consoles and mobile platforms. Its work combines technical simulation development with a wider history of family games, licensed entertainment properties, strategy titles and console conversions.

The studio provides full-cycle game production alongside co-development and platform adaptation. Its capabilities cover game design, software engineering, 3D art, animation, environmental level design, quality assurance, compliance testing, localization and post-launch support. Cross-platform engineering is a central part of its work, including adaptations for Nintendo Switch, PlayStation and Xbox, as well as iOS and Android development.

Simulation development and console adaptations

The studio’s simulation work includes Seafarer: The Ship Sim, a naval simulation developed as its principal in-house project, and co-development of Construction Simulator 4 for Nintendo Switch and mobile devices. Earlier projects include console editions of Construction Simulator 2, Construction Simulator 3, Fishing: Barents Sea and Fishing: North Atlantic.

Its adaptation portfolio also includes Nintendo Switch editions of Railway Empire 2, Tropico 6, Dungeons 3 and Port Royale 4. Beyond simulations, the studio has worked on games based on properties such as Bibi & Tina, Bibi Blocksberg, Schleich bayala and BIG-Bobby-Car. Its longer production history includes strategy games such as Against Rome and WarCommander, reflecting a portfolio that extends across several genres and generations of platforms.

Company development

Over its operating history, the studio has developed, co-produced or ported more than 250 commercial games and applications. astragon Entertainment acquired the company in April 2023 to expand its in-house development capabilities and strengthen proprietary simulation projects. The continuing business adopted the name astragon Development in May 2025. It operates within the wider everplay group while retaining its role as the Hamm-based game development company.
