Warhammer 40,000: Mechanicus II Save File Location

Last verified: 2026-10-01

Save file location (Windows (Steam)): %USERPROFILE%\AppData\LocalLow\BulwarkStudios\Mechanicus II\Saves

Quick answer: On PC, Warhammer 40,000: Mechanicus II (Bulwark Studios, Unity) follows the original Mechanicus convention: saves live under %USERPROFILE%\AppData\LocalLow\BulwarkStudios\. For the original Mechanicus the verified path was %USERPROFILE%\AppData\LocalLow\BulwarkStudios\Mechanicus\Saves\, so Mechanicus II is expected under %USERPROFILE%\AppData\LocalLow\BulwarkStudios\Mechanicus II\Saves\ (or a similar product folder). Hard saves are numbered 0, 1, 2…; autosaves carry a -xyz suffix. This is the Unity LocalLow location, NOT Documents and NOT the Steam install folder. If the exact product folder name differs, open %USERPROFILE%\AppData\LocalLow\BulwarkStudios and look for the newest subfolder with a Saves tree. Steam Cloud mirrors these files, so a bad sync can overwrite a good save — copy the Saves folder before verifying files or switching PCs.

Warhammer 40,000: Mechanicus II is a Unity tactics game from Bulwark Studios, so — like the original Mechanicus — your saves are not in Documents or the Steam install folder. They sit in the AppData\LocalLow\BulwarkStudios tree. Here is the exact PC path, how to open it, and how to back it up before a bad Steam Cloud sync.

Save file locations

Windows (Steam)
%USERPROFILE%\AppData\LocalLow\BulwarkStudios\Mechanicus II\Saves

Expected full path: C:\Users\<you>\AppData\LocalLow\BulwarkStudios\Mechanicus II\Saves\ . Unity stores under LocalLow (not Local, not Roaming). Mirrors the verified original path ...\LocalLow\BulwarkStudios\Mechanicus\Saves. Hard saves 0,1,2…; -xyz = autosaves.

AppData\LocalLow (name variant)
%USERPROFILE%\AppData\LocalLow\BulwarkStudios

If a 'Mechanicus II' folder is absent, open %USERPROFILE%\AppData\LocalLow\BulwarkStudios, sort by date modified, and find the newest subfolder containing a Saves tree.

Steam Cloud
Managed by the Steam client

The original Mechanicus used Steam Cloud; Mechanicus II is expected to as well. Steam syncs on launch/exit — going online after a crash can pull an older cloud save over your newer local one.

Cloud saves

Mechanicus II is expected to use Steam Cloud (as the original Mechanicus did). Steam uploads on exit and downloads on launch, so a corrupted or half-written save can overwrite your good cloud copy on the next launch. Keep a manual copy of the %USERPROFILE%\AppData\LocalLow\BulwarkStudios\Mechanicus II\Saves folder as your real backup, outside the game directory.

Cloud save conflict & platform recovery

The common loss is 'my campaign rolled back' after a crash or a session on another PC — Steam Cloud synced an older save over the newer one.

  1. Before relaunching after a crash, copy %USERPROFILE%\AppData\LocalLow\BulwarkStudios\Mechanicus II\Saves to a safe folder.
  2. In Steam, right-click Mechanicus II → Properties → General and temporarily disable Steam Cloud, then launch to confirm the correct local save.
  3. If the local copy is good, keep cloud off, verify in-game, then re-enable Steam Cloud so the good save uploads.
Back up first (Windows) — copy & run

FAQ

Where is the Mechanicus II save file on PC?

Expected at C:\Users\<you>\AppData\LocalLow\BulwarkStudios\Mechanicus II\Saves\ — the Unity LocalLow location, mirroring the verified original path ...\LocalLow\BulwarkStudios\Mechanicus\Saves. Not Documents, not the Steam install folder.

Does Mechanicus II use cloud saves?

It is expected to use Steam Cloud, as the original Mechanicus did. Steam syncs on launch and exit, so keep a manual copy of the Saves folder in case a bad sync overwrites a good save.

Which Mechanicus II save files are autosaves?

As in the original, hard saves are numbered 0, 1, 2…, while files with a -xyz suffix are autosaves. Back up the whole Saves folder to keep both.
