Overview

Native ultrawide is listed as supported on PCGamingWiki. It is a map strategy game with no FOV option. PCGamingWiki says the UI does not scale with resolution (experimental UI scaling exists) and multi-monitor setups need a hacky windowed workaround that may crash on launch. We could not verify cutscene or 32:9 layout, so those fields are conservative.

Patch history & verification

1.19.3Sep 20, 2026
Verified PCGamingWiki (ultrawide = true via Steam curator reference, multi-monitor hackable) and Steam patch 1.19.3. Checked the Flawless Widescreen public repo (fws_repo.xml) on 2026-09-20: no module for this game. Could not confirm 32:9 behavior.
