Analysis — Ace Combat Assault Horizon - Enhanced Edition on the Steam Machine

What to expect

Ace Combat Assault Horizon - Enhanced Edition has no SteamOS rating yet. A similar game we do rate, ACE COMBAT 7: SKIES UNKNOWN, lands green on the Steam Machine — a reasonable first guide until this one gets its own verdict.

On the couch

Steam lists only partial controller support — some menus or modes may still want a mouse, and Steam Input's community layouts are the first thing to try.
