Heeheehee! Guess I did kinda put it that way, didn't I? Didn't mean nothin' by it. You lot, you got skills. Like them Vault Hunters. This ain't nothin' ya can't handle.

The desert though, that's suicide. You got safety here. Just gotta defend it. Think of the infected like big, gross, rabid guard dogs. The walls keep the infected out and the infected keep the bandits out. Mostly.
