Half-Life: Cross Product Multiplayer drops native Linux support for Season 10

With the launch of Season 10: Uplink on July 24, native Linux client support for Half-Life: Cross Product Multiplayer is being discontinued. Moving forward, the Windows version running through Proton 10 is the supported method for playing on Linux-based systems.

The change does not affect dedicated servers—Linux-based server binaries remain natively supported, so existing operators can update and continue hosting without disruption. Players using SteamOS, Steam Deck, or standard Linux distributions can still play; Season 10 has been tested with Proton 10 and Steam will automatically select the correct configuration. Minor viewmodel texture glitches may occur on rare occasions.

The Open Beta has also been deactivated. Aura Tech states that while native Linux support is ending for the time being, they are open to bringing it back if future circumstances allow. For now, focusing on a single client is the most practical approach, with Proton ensuring continued playability across Linux devices.
