Last Epoch drops the Native Linux version, devs tell players to use Proton

Without any warning, Eleventh Hour Games have completely dropped support for and completely removed the Native Linux version of Last Epoch.

Initially, the patch notes didn't even mention Linux at all, but were later updated with the Steam Deck section expanded to include the notice. In the changelog they state "We’re no longer building a native Linux client and recommend Linux players use Proton on Linux which provides a much better experience".

For people who purchased specifically because it was advertised and sold on having a Native Linux version, it's not great and their communication after the fact is not a good look either. That said, Valve's Proton often really does offer a better experience. A lot of the time because of various game engine issues and/or just not a lot of time spent improving the Linux version. So Linux desktop and Steam Deck players can thankfully still play the game. From what I've seen, many players were already using Proton for it due to various problems.

The game currently has a Steam Deck Playable rating with Proton 9.

As for their promised Steam Deck improvements, they have now added UI scaling options with the latest update. However, a recent announcement noted they've pushed back some other changes as they "feel it’s important that when we say we are Steam Deck verified, players can trust that the experience they will receive on the Steam Deck is up to snuff with our expectations for player experience". So more to come there in future.
