Behind the scenes
The name of this challenge is a reference to Blade Runner. Specifically, it refers to Rick Deckard's statement given to Rachael: "Replicants are like any other machine. They're either a benefit or a hazard. If they're a benefit, it's not my problem." In addition, the 5.56mm Pistol and That Gun are both modeled after Deckard's pistol.
