Fortis Games

Fortis Games is a global video game developer and publisher founded in 2021 by Steven Chiang, Shawn Foust, and Calvin Lau. Formally announced in March 2022, the company develops and publishes live-service games for mobile and connected platforms, with an emphasis on social mechanics, community infrastructure, and ongoing player experiences.

The studio operates as a unified, remote-first organization rather than a federation of independently run teams. It expanded its international development capacity at launch through the acquisition and integration of Portugal’s Doppio Games, Brazil’s Oktagon Games, and Romania’s Metagame SRL. Their teams and leadership were incorporated into Fortis’s operating structure.

Games and development focus

Fortis’s work combines games-as-a-service architecture with player analytics, live operations, publishing technology, community management, and trust-and-safety moderation. Its capabilities include:

• Full-cycle game design and production
• Mobile game development and publishing
• LiveOps tooling and management
• Social gaming mechanics and community systems
• Cross-platform architecture and interactive media
• Conversational and voice interaction systems

Its commercial portfolio includes Twilight Towers, also released as Twilight Towers: Merge Defense, a free-to-play mobile title combining merge progression, tower-defense strategy, and tactical dragon battles. The game has received ongoing seasonal updates, including the Steel and Stone Update 4.0 and Thunder and Lightning Update 5.0.

Fortis also developed Bloom & Breakfast: Merge Town, a narrative-driven cozy merge-simulation adventure.

Ownership and operating model

Fortis Games operates legally in the United States as Fortis, LLC and is a wholly owned operating subsidiary of Las Vegas Sands Corp. Its international organization includes legal operating entities in the United Kingdom, Portugal, Brazil, and Romania, supporting game development, publishing, engineering, and production activity across its global team.
