Wild Wasteland is a trait in Fallout: New Vegas. It adds (and in some cases changes) random encounters and locations to include the dark humor more reminiscent to that of Fallout, Fallout 2 and Fallout Tactics special encounters. Not having this trait will make fewer humorous analogues in places of the Wild Wasteland encounters. Events that are modified/triggered by Wild Wasteland are indicated by an "alien-esque" sound and an on-screen "..." message with an image of the Vault Boy with spirals for eyes, identical to the Wild Wasteland image.
