So I have gone through and killed all the nightkin, including Davidson. I met the sniper ghoul, had already found his girlfriend and he left. Now I am trying to get back into the research labs to report back and the door won't let me in. It says a key is required. Using the intercom results in a "stop using the intercom" message.
I have seen this issue on other sites, but did not see it here. What am I missing to finish this one?
Thanks.
Maybe you screwed up or that particular part of the quest is bugged. I've completed that quest but I took a different path. Spoilers ofcourse****** Instead of killing davidson, just help him out. You still have to kill nightkins who come in your path but you can help out both the ghoul and davidson and they they leave on their own accord. Once you choose to help davidson, he gives you a key.
I had no problems completing this mission. If your speech skills aren't high enough then I suggest you just restart the whole mission again. Go to a prior save file and do it again. If the same thing happens again then wait for another patch lol, if you don't have another save file then I guess you're screwed buddy.
