Return to Castle Wolfenstein Secrets: How Hidden Areas Work
On this page
Short answer: Return to Castle Wolfenstein has no hidden levels, but its single-player campaign (27 levels across 7 missions) hides secret areas and treasure in each level. The end-of-level screen tells you whether you found them all. On Xbox, finding every secret in a level earns a Secret Bonus; on PS2, secrets pay for items at the end of each level.
How secrets work in each version
| Version | What secrets do |
|---|---|
| PC (2001) | Secret areas and treasure in each level; the results screen shows how many you found. |
| Xbox: Tides of War (2003) | A Secret Bonus after each level in which you found every secret area. This version also adds two-player co-op. |
| PS2: Operation Resurrection (2003) | The secrets you find let you buy items at the end of each level. |
Tips for finding them
- Check the results screen after each level: if a secret is missing, replay that level rather than the whole mission.
The German release originally removed Nazi symbols and renamed the Third Reich the “Wolf Clan”. For the modern series, see Wolfenstein: The New Order secrets. More guides: all Wolfenstein guides.
