Forum:Trouble With The Experimental MIRV

I not sure what to do so i thought i would ask. I have all 5 of the Kellers holo-tapes (1 to 5) and have listened to them in order but for some reason i cant acsess the bunker in the national guard depot. Am I doing something wrong? Any and all help welcomed.

(This is my first ever post on this fourm so if i did something wrong point it out, so I can learn from my mistakes)
