Raiders

If you complete the Vault City Chief of Security's mission to scout the road to the NCR, you'll encounter a raider camp along the way. There are two ways to get there: through a trap-lined cave, and through a secret passage. The safe can be opened by collecting all the captain's tags in your inventory. Be careful, the safe is booby-trapped. Search for  the Sierra Outpost  or head straight to  the NCR .

Editor's note: The safe contains incriminating evidence against Bishop for Vault City.
