Beatrix roguelite board-builder demo launches with Steam Deck and Linux support

Tambù Digital has released a demo for Beatrix, a dark fantasy roguelite board-builder game, as part of Steam Next Fest running through October 26, 2026. The studio states it tests games on Steam Deck and Steam Machine to ensure Linux compatibility, but native Linux releases are not planned due to resource constraints; Linux support relies on the Windows build running via Proton. The demo includes a new in-game guide, tuned pacing, combat fixes, menu polish, and audio adjustments. The full release is scheduled for Q1 2027. Gameplay emphasizes positional card placement on a grid, with mechanics like boxing in enemy cards to convert them and Canon rules that modify the board state.

What Beatrix offers Linux and Steam Deck players

• Proton-based Linux support: The studio tests on Steam Deck and Steam Machine hardware but does not provide native Linux builds; compatibility depends on the Windows version running through Valve's Proton compatibility layer.
• Unity engine: The game is built with Unity, which has known Proton support but can have varying compatibility depending on Unity version and middleware choices.
• Steam Next Fest integration: The demo release is timed with Steam Next Fest (ending October 26, 2026), a common discovery event for upcoming titles.
• Onboarding improvements: The new demo adds an in-game guide and adjusted early-game pacing to reduce the learning curve for the board-building mechanics.
• Grid-based positional mechanics: Unlike traditional deck-builders, card placement on the board directly affects combat outcomes, with systems for converting enemy cards and dynamic rule modifications via Canons.

Why it matters

For Linux gamers and Steam Deck owners, Beatrix represents another data point in the ongoing shift toward Proton as the default compatibility path rather than native ports, reflecting the resource pressures facing small studios. The claimed Steam Deck testing, if accurate, may provide a smoother experience than untested Proton titles, but the lack of native builds limits transparency and debuggability for Linux-specific issues. The board-builder genre remains underrepresented on Linux, making this demo a useful test case for players interested in positional deck-building mechanics.
