For some reason, whenever the Enclave robots in the Oil Rig shoot me on sight, I can kill the ones next to the reactor entrance and nothing happens, however, If I try to kill the ones on the way out (The room northeast from the entrance to the oil rig), the soilders wearing the T-51b's shoot me, which I can't possibly beat. I asked bethesda support, but I didn't really exepect to get anything though, because they didn't develop the classic games. And I was right, I am quoting this from the response: " The Enclave don't take too lightly of who they want at that location. You may have to have another plan to get inside." I know this isn't true because on my first playthrough where I got to the oil rig, they didn't shoot me at all, also, it's worded as if I'm outside and trying to get in, finally I know there is no other way to the bottom floor other than through the Robots.
