Hyperion’s New-U stations in Borderlands 2 will automatically scan and store your molecular structure data whenever you approach one, even if you don’t want it to. But you probably will, since when you do finally fall to the vicious inhabitants of Pandora, the last New-U station you passed will automatically digi-struct a brand new you (for a small reconstruction fee)!
Major New-U stations in each area are linked into Pandora's Fast Travel network. Activate a Fast Travel station to instantly digi-struct a new you at any Fast Travel New-U stations you’ve been scanned at. Yes, there’s the pesky ethical quandary of “are you really still the same person,” but hey! Fast travel!
