There is no legitimate free Linux download of Among Us — buy the $5 PC copy and run it with Proton

Asked (summary):

Find a free download of Among Us for Linux, similar to a third-party free-games site.

Three official routes were checked — the paid PC edition, its Linux compatibility record, and the free mobile edition — each backed by a distinct source, as of 30 September 2026. No native Linux PC build exists, free or paid.

Recommendation: buy the official PC copy (about US$5, price varies by region) and enable Steam Play/Proton on Linux. ProtonDB rates it Playable, with online multiplayer reported Excellent.

Native Linux: the official Steam and itch.io listings are Windows-only; Innersloth ships no Linux PC build.

Windows build through Proton: the Windows version runs on Linux through Steam Play/Proton. Most reports succeed with Proton 10, Proton Experimental, or GE-Proton; a minority of setups need a different Proton version, a 32-bit driver package, or a launch option for mods.

Free mobile edition: the only official free-to-play version is the ad-supported Android/iOS mobile edition — not a Linux PC download.

Stay clear of third-party “free download” sites. Pages offering a free PC copy of Among Us are unauthorized; files from them may be pirated, tampered with, or malicious. This report does not link such sites.
