Despite Halo Infinite being unsupported on Steam Deck due to “anti-cheat”, by using a new driver one owner has managed to get Master Chief’s latest outing up and running on the portable PC.
Sharing some gameplay on reddit, DanTheBloke (via exputer) explained that the latest update to Proton GE has allowed them to get online play for Halo Infinite working on their Steam Deck through the beta SteamOS.
DanTheBloke does say gameplay “can be a little janky” and there is “some clipping audio at times”. Regardless though, it is definitely still playable, as you can see for yourself below.
