Orcthall horde survival roguelite announces Steam launch and planned Linux port

RedKar Devs has announced the upcoming release of Orcthal, a horde survival roguelite where players lead orc raids against human settlements. The game is scheduled to launch on Steam on November 16, 2026, with Windows serving as the primary initial platform.

While a native Linux build is not included in the initial launch, the developer has confirmed that a Linux port is on the roadmap. Because the game is built using the Unity engine, the developer intends to leverage that framework to facilitate the porting process once testing hardware is established.

Development and Linux Compatibility

• Engine Framework: The game is developed using Unity, which provides a standardized pathway for cross-platform deployment and potential native Linux builds.
• Proton Compatibility: A free demo is currently available on Steam, allowing Linux users to test the game's performance via the Proton compatibility layer ahead of the full release.
• Planned Porting Path: The developer intends to set up dedicated Linux testing hardware to evaluate performance before committing to a native version.
• Multiplayer Architecture: The title features online co-op support for up to four players, which will require stable networking performance under Linux/Proton environments.

Why it matters

The availability of a Steam demo allows Linux gamers to immediately assess Proton compatibility for this title. If the planned native port follows the Unity engine's standard capabilities, it could provide a smoother experience for Steam Deck users and those on various Linux distributions.
