BloodRush: Undying Wish 1.0 launches December 3 with native Linux and Proton Steam Deck support

Lightmancer Studios has announced that BloodRush: Undying Wish 1.0 will exit Steam Early Access on December 3, 2026, with native Linux support alongside Windows. The Brazilian developer's fast-paced hack-and-slash roguelike, built in the Godot engine, will be playable on Steam Deck through Proton, representing a split release strategy where the handheld version relies on Valve's compatibility layer rather than a native Linux ARM or Deck-specific build.

The 1.0 release concludes the game's Early Access period, which saw more than 30 patches addressing combat tuning, skill reworks, and technical improvements. New content for the full launch includes a final boss encounter, an additional weapon, and resolution of key story arcs. The game currently holds a 97% positive review rating on Steam at a $9.99 USD price point.

Linux release structure and Steam Deck compatibility

• Native Linux build: The game will ship a dedicated native Linux version separate from the Windows build, rather than relying solely on Proton for desktop Linux users.
• Steam Deck via Proton: Handheld compatibility is explicitly confirmed to run through Steam Play/Proton, with no native Steam Deck or Linux ARM build mentioned.
• Godot engine foundation: The game is built using the Godot engine, an open-source game engine that has seen growing adoption among indie developers targeting Linux.
• No performance data disclosed: The source notes absence of frame rate targets, Steam Deck verification status, or hardware test results for the Proton path.
• Early Access technical iteration: Over 30 patches during Early Access addressed bug fixes, combat balance, skill system reworks, and underlying technical improvements.

Why it matters

The split native-Linux-desktop versus Proton-for-Deck approach illustrates how smaller studios are navigating Valve's ecosystem, treating Proton as the pragmatic path for handheld while still delivering native builds for traditional Linux gaming. For the Godot engine community, another commercial title shipping native Linux reinforces the engine's viability as a cross-platform tool, though the lack of Steam Deck Verified status or performance disclosures leaves practical compatibility questions unanswered until launch.
