Tactic Studios

Tactic Studios is an independent Canadian video game developer based in London, Ontario. Founded in 2007 by Jesse Attard, the studio develops games and proprietary engine technology for PC and consoles. Its work spans turn-based tactical role-playing games, narrative puzzle adventures and asymmetrical multiplayer action, with internal engineering providing a technical foundation across these different genres.

Central to its development approach is the Immortal Engine, a proprietary engine that the studio builds and maintains rather than relying on a commercial third-party engine. The technology evolved from the architecture behind its early tactical game into a full 3D, multiplatform engine. This progression connects the studio’s game development with its ongoing work on rendering, physics and interactive systems.

From tactical RPGs to multiplayer action

The studio’s debut title, Immortal Empire, entered open beta in 2009 before receiving a full commercial Steam release in December 2015. The multiplayer fantasy RPG combines turn-based tactical strategy with character customization, and its development helped establish the studio’s original engine architecture.

Claire de Lune followed in July 2021 on Steam and the Epic Games Store. A first-person science-fiction puzzle adventure, it brought the studio’s technology into a story-driven 3D format and demonstrated a different application of its internal engine development.

In February 2026, Tactic Studios released KILLER INN into Steam Early Access through a collaboration with Square Enix and Tokyo Broadcasting System Television. The online asymmetrical PvP action shooter combines combat with social deduction, deception and murder-mystery mechanics. The project extends the studio’s portfolio into multiplayer action while building on its game development and technical capabilities.

Across its projects, Tactic Studios undertakes full-cycle game development, from pre-production through production and post-launch operations. Its activities also include proprietary engine engineering and collaborative development and publishing partnerships.
