Well, that will teach you for going around and killing everyone... Its possible to get the commander to give it to you if you set up the right story.
I think you're going to need more lockpick skill. A lot more.
its not like i had much of a choice, the minute i walked in after passing the speech check with the front doorman she immediately attacked me for no other reason, not even dialogue. is it even confirmed to be in that locker? did the commander have the key to the locker?
also i want to know how high people's lockpick skill was when they unlocked the FOB locker. any takers? and less people telling me im stupid for defending myself for the 50th time?
