Both specs are quoted from the Steam store page. Linux is a listed platform alongside Windows; macOS is not. The 3 GB install and a GT 1030 floor make this one of the lightest 2026 releases on the store — the demanding part is the art, not the simulation. Steam Deck: Valve has not published a compatibility rating for Sovereign Tower as of September 1, 2026, so this site does not claim one.
