In order to play with friends on Windows I had to replace the ucrtbase.dll files in the wine prefix as detailed here: https://web.archive.org/web/20250724035426/https://www.reddit.com/r/SteamDeck/comments/11dftq1/fix_halo_mcc_coop_between_windows_and_linuxsteam/
Playing through the Halo 3 campaign, we ran into significant performance issues on a regular basis. Very severe stuttering at times, sometimes related to effects like rain, but between those stutters it ran fine.
Needed to replace DLL files to play with friends on Windows, and it seemed to be inconsistent about who could host games, but overall it was alright. Only played co-op campaign with anti-cheat disabled.
Without the tinkering the game can realistically only be played solo, so it's hard to recommend out of the box. But the fix isn't complex, just annoying, so if you're craving Halo there isn't much reason to avoid.
