Overview
Below Zero supports 21:9 natively and has both vertical and horizontal FOV sliders. The HUD spreads to the screen edges, which is awkward on very wide screens. PCGamingWiki points to the HudConfig mod to move it.

Patch history & verification
2025 PatchSep 23, 2026
Verified PCGamingWiki (ultrawide true with a HudConfig note, FOV sliders). I marked 32:9 partial to be safe because I found no direct 32:9 test. Cutscene and menu values are lower confidence. HudConfig is listed only as an alternative because I could not confirm it works with Below Zero. Not in the Flawless Widescreen repo (the original Subnautica entry does not cover Below Zero).
