Halo: Campaign Evolved 100% Save File for PC + Save Location
Halo: Campaign Evolved
Save File Overview
The halo campaign evolved save file is aimed at players who want a completed PC campaign state without replaying the full grind from the beginning. Halo: Campaign Evolved has 13 campaign missions, including the three new Operation: METEORITE missions, and its collectible system includes 39 mission Skulls plus three extra Skulls tied to Campaign Remix. A proper 100% save should give you a finished campaign state with the relevant campaign missions completed and collectible progress available according to the supplied save. Don't assume that a downloaded save automatically includes every possible achievement or every cosmetic item unless the actual file has been checked. Halo: Campaign Evolved also supports four-player online co-op and shared progression between PC, Xbox Series X|S, and PlayStation 5. Steam requires an Xbox Network account linked to the Steam account. If you're replacing an existing save, back it up first. The safest move is simple: close the game, copy your current SaveGames folder somewhere else, then replace the files.
System Folder Location for Save Data
%LOCALAPPDATA%\Meteorite\Saved\SaveGamesClose Halo: Campaign Evolved before touching the save data. If Steam is running, closing Steam as well can help prevent cloud synchronization from restoring an older state during the replacement. For Steam, press Win + R, paste %LOCALAPPDATA%, and press Enter. Open Meteorite, then Saved, then SaveGames. This is the folder PCGamingWiki currently lists for Windows save data. If you don't see the folder, launch the game once, create or advance a campaign save, exit normally, and check again. This gives the game a chance to create its expected local save structure. For Xbox app/Game Pass, don't assume the Steam path applies. Windows-protected save storage can be harder to browse and may use a package-specific SystemAppData\wgs directory. Before replacing anything, identify the existing save folder and make a complete copy of it. Your final check should be that the Steam version contains the SaveGames folder under Meteorite\Saved.

Halo: Campaign Evolved released on PC on July 28, 2026 and is available through Steam and Xbox on PC/Game Pass. Xbox Play Anywhere provides shared progression across supported Xbox and Windows PC versions, while Steam is a separate storefront installation and requires an Xbox Network account connection. For the Steam PC version, the save-game data is stored under %LOCALAPPDATA%\Meteorite\Saved\SaveGames. PCGamingWiki lists Steam App ID 2806050 for the game. The Xbox app/Game Pass version should be treated separately when replacing files. Microsoft Store-style PC games can use protected Windows save storage, and community reports for Campaign Evolved point to the protected SystemAppData\wgs structure rather than the normal Steam SaveGames folder. Don't copy a Steam save blindly into the Xbox app version. Cross-progression exists, but that doesn't mean the underlying local files are interchangeable. If a save doesn't appear, first confirm the storefront, signed-in Xbox account, save folder, and game version.
How to Apply This Save File Correctly
Essential Save File FAQs
Can I use this Halo: Campaign Evolved save on Steam and Game Pass?
The game supports shared progression between PC platforms, Xbox consoles, and PlayStation 5, but the local save locations differ. Steam uses %LOCALAPPDATA%\Meteorite\Saved\SaveGames, while the Xbox app/Game Pass version can use protected Windows save storage. Don't treat a Steam file copy as automatically compatible with the Xbox app version.
Why is my Halo: Campaign Evolved save file not working?
Check the storefront first. For Steam, confirm that the files are inside %LOCALAPPDATA%\Meteorite\Saved\SaveGames. Then make sure the game is fully closed during the replacement and check whether Steam Cloud restored your previous data. If you're using Game Pass, don't use the Steam folder as a substitute for the protected Xbox save system.
What does the 100% save contain?
The intended page target is a 100% completed PC save. Halo: Campaign Evolved has 13 campaign missions, 39 collectible Skulls, and 13 Terminals. The official Halo support page confirms three Skulls and one Terminal per mission, with Campaign Remix becoming available after collecting any three Skulls. Exact achievement, Skull, Terminal, difficulty, and optional challenge status should be confirmed against the actual supplied save rather than assumed.
Preventing Progress Loss: Backup Reminders
Back up %LOCALAPPDATA%\Meteorite\Saved\SaveGames before replacing a Steam save. Copy the whole folder to another location, such as a folder named Halo Campaign Evolved Backup, instead of copying only one file. This gives you a simple rollback: close the game, remove the replacement files, and restore your original folder. Steam Cloud can interfere with replacement saves if the cloud copy and local copy don't match. If the game immediately restores your old progress, check Steam's cloud-save prompt and make sure you're deliberately keeping the local replacement rather than accepting the older cloud copy. Halo: Campaign Evolved also supports shared progression across supported PC, Xbox, and PlayStation platforms, but storefront-specific local save formats shouldn't be assumed to be interchangeable. The game uses an Xbox Network account on Steam, so make sure you're signed into the intended account. Never run an .exe just to install a normal save. A save replacement should consist of save data files and normal file operations.
Summary
This halo campaign evolved save file is built around the PC 100% save-file search intent: get a completed campaign state, locate the Windows save folder, replace the files correctly, and keep the original progress safe. For Steam, the main location is %LOCALAPPDATA%\Meteorite\Saved\SaveGames. The Xbox app/Game Pass version needs separate handling because protected Windows save storage can use a different structure. Halo: Campaign Evolved has 13 campaign missions, 39 collectible Skulls, and 13 Terminals, so a genuine 100% claim should be checked against those systems rather than assumed from the filename. Before replacing anything, copy your existing save folder somewhere safe. Then install the replacement, launch the game, and verify the campaign progress before removing that backup.
