Everlast: Undying Tale launches Linux and Steam Deck support in Early Access

Everlast: Undying Tale, an open-world fantasy action RPG developed by InSpades using the Unity engine, launched into Steam Early Access on October 30, 2026 with support for Linux, Steam Deck, macOS, and Windows. The game is priced at $19.99 USD with a 20% launch discount and currently holds a 96% positive review rating on Steam. Players can explore the world of Sarkis solo, in private co-op sessions, or on shared servers supporting up to 100 concurrent players, with gameplay spanning combat, crafting, fishing, and dynamic world events.

The Linux and Steam Deck launch is notable for expanding the platform's RPG catalog, though the announcement lacks technical specifics. No Steam Deck compatibility rating (Verified, Playable, or Unsupported) is provided, and the store page does not clarify whether the Linux build is native or relies on Proton. Handheld support is mentioned in the Steam community forum, suggesting developer awareness of portable play but leaving performance and controller optimization questions unanswered during the Early Access period.

Linux and Steam Deck technical status

• Platform support: The game lists Linux, Steam Deck, Mac, and Windows on its Steam store page, indicating a multi-platform Unity build with Linux as a first-class target.
• Steam Deck verification gap: No Steam Deck compatibility rating is assigned, leaving uncertainty about native resolution targeting, controller glyph support, text legibility, and whether Proton is required.
• Proton status unclear: The announcement and store page omit whether the Linux build is native or Proton-mediated, which affects troubleshooting expectations and performance baseline comparisons.
• Server architecture: Private games and 100-player shared servers are supported, with dynamic events propagated through the map and quest log systems; Linux client compatibility with these server types is untested in public reports.
• Engine foundation: Built on Unity, which has established Linux export pipelines and Steam Deck-specific rendering paths, though individual titles vary in optimization quality and input handling.

Why it matters

The addition of another open-world RPG to Linux and Steam Deck broadens the platform's commercial viability for mid-size Unity studios, particularly in the persistent Early Access market where player feedback drives development. For Linux gamers, the lack of explicit Proton or Deck verification details means purchase decisions carry more uncertainty than with titles that have undergone Valve's formal certification process, highlighting ongoing gaps in how developers communicate technical readiness for handheld Linux gaming.
