Passtech Games

Passtech Games is a Villeurbanne-based French video game developer founded in 2012 by Sylvain Passot. The studio creates tactical, action-focused games for PC and consoles, with a catalogue spanning real-time strategy, tower-defense hybrids, isometric action adventures and roguelikes.

Its early releases include Space Run and Space Run Galaxy, which combined real-time management and tower-defense ideas. The studio later released Masters of Anima, an isometric action-adventure game built around tactical summoning mechanics.

Roguelike and action development

Passtech Games gained wider international attention with Curse of the Dead Gods, a dark action roguelike recognised for its combat, curse systems and dynamic lighting. It followed that release with Ravenswatch, a co-operative top-down action roguelike that entered Steam Early Access in 2023 and reached a full multiplatform release in 2024.

Capabilities

The studio's work encompasses:

• Full-cycle game development and systems design
• Gameplay, engine and rendering programming
• 3D art direction, character and environment modelling, and VFX
• Multiplatform production and porting for PC, PlayStation, Xbox and Nintendo Switch
• Post-launch live-content updates and iterative, community-informed design

Passtech Games became a wholly owned subsidiary of French publisher Nacon in April 2021. It continues to operate as an active studio under founder Sylvain Passot, developing action-oriented games with an emphasis on replayability, tactical decision-making and responsive combat.
