[FO2] so is there a (narrative) reason there's a blue pass key in Gecko?
My first thought was that since both the Gecko plant and Navarro are Poseidon Energy, they might use the same infrastructure, and that almost explains why a pass key found at the former might be usable at the latter, but it's still the electronic equivalent of making a bunch of locks with standardized pins.
Gameplay-wise it just... feels weird? Like it doesn't actually let you infiltrate the base because the door guard will still stop you from the other side (but does still assume you're with the Enclave) so all you can do is free Xarn. Not that I'm strapped for options regarding infiltrating Navarro, mind you, it just feels kinda weird to specifically go halfway in terms of rewarding the Jamrock Shuffle like that.
