Puzzle thriller The Transference launches on Steam Deck via Proton with Verified status

The Transference, a first-person mystery thriller built in Unreal Engine 5 by Spanish solo developer Kuraishisama and published by JanduSoft, has launched on Steam with day-one Steam Deck compatibility. The game runs on Linux and Steam Deck through Proton rather than a native Linux build, and has received Valve's Steam Deck Verified badge. Players navigate a locked-house escape scenario incorporating logic puzzles based on the Tower of Hanoi and Dining Philosophers problem, a Spanish card game variant, and narrative elements drawn from Andalusia folklore and Spanish literature.

The title is priced at $9.99 USD with a 20% launch discount, and features full English and Spanish voice acting, adjustable stress levels, and stealth mechanics without jump scares. The Steam Deck Verified status indicates Valve's testing found controller support, readable text, and functional gameplay on the handheld, though the Proton-based compatibility means performance characteristics depend on Proton and DXVK/VKD3D-Proton translation layers rather than native Vulkan or OpenGL paths.

Proton compatibility and Steam Deck verification details

• Compatibility layer: The game runs on Linux and Steam Deck via Proton, not through a native Linux port or build, placing it in the Windows-on-Linux translation path used by the majority of Steam Deck's catalog.
• Steam Deck status: Valve has assigned the title Steam Deck Verified, indicating functional controller support, legible interface text, and no launch-time compatibility interventions required on the handheld.
• Engine foundation: Built on Unreal Engine 5, the title relies on Proton's DXVK or VKD3D-Proton components for graphics API translation from DirectX 12 to Vulkan, with Mesa RADV as the likely driver on Steam Deck's AMD APU.
• Platform pricing: Launch pricing is set at $9.99 USD / £8.79 / 9,99€ with a 20% discount, with no separate Linux SKU; the Windows purchase grants cross-platform access through Steam Play.

Why it matters

Each additional Unreal Engine 5 title achieving Steam Deck Verified status through Proton expands the empirical base for how UE5's Nanite, Lumen, and DirectX 12 dependencies perform under translation layers on AMD RDNA2 mobile hardware. For Linux gamers, this reinforces Proton as the dominant delivery mechanism for commercial titles while continuing to leave native Linux ports as a minority path, particularly among smaller studios where solo development resources preclude maintaining separate build targets.
