Where Are Halo Infinite Save Files Located?
Halo Infinite campaign saves live in Steam userdata on PC and in a wgs sandbox for Xbox-app builds.
Last updated
Halo Infinite splits by store like many Xbox titles. Steam builds keep campaign saves in userdata under app ID 1240440. Xbox-app builds live sandboxed in the Packages tree with automatic cross-device sync.
Multiplayer progression is server-side either way. Local backups matter for campaign checkpoints and settings; copy the matching tree with the game closed. Skull collectibles ride in the same saves.
Where Halo Infinite stores this, by platform
C:\Program Files (x86)\Steam\userdata\[SteamID]\1240440
Campaign saves under userdata/1240440. Xbox-app builds sync via account; Steam builds via Cloud. Copy closed in both cases.
~/.local/share/Steam/userdata/[SteamID]/1240440
Proton prefix for app ID 1240440; the userdata tree is shared, not per-prefix. Same closed-game rule on Deck.
Frequently asked questions
How do I back up Halo Infinite campaign saves?
Copy the whole userdata/1240440 tree with the game closed. Xbox-app builds sync automatically across machines signed into the same account.
Does Halo Infinite sync between PC and Xbox?
Yes for Xbox-app builds via account sync. Steam builds rely on Steam Cloud over the userdata tree; keep both enabled and the game closed during copies.
