Overview
By default the game keeps horizontal FOV, so ultrawide crops the top and bottom (Vert-). Changing AspectRatioAxisConstraint from MaintainXFOV to MaintainYFOV in XComEngine.ini makes it Hor+, per both PCGamingWiki and WSGF. WSGF reports the HUD spans the width, some dialog boxes shift left or right, and the red alien-activity overlay is 16:9 centered. Cutscene behavior was not confirmed.
