Alright, so I'm at the stage in the game where I need to go to The Fort and go to the bunker and such where Benny is

From what I've read though I should have gotten an invite from Caesar at this point from Vulpes Inculta, however I killed him back when I first met him in Nipton.

Is there any other way to get an invite or otherwise jump-start this train of thought so I can get to The Fort without having to carve my way through oodles of soldiers or is that what I'm going to have to do?

If you could figure out Vulpes reference ID, that would do it. But nobody seems to know how to?

I was thinking along those lines as well.

Is there anyway to possibly manually start the quest Render Unto Caesar and from there I can go to the fort and talk to Caesar and do all that.

If I have to carve my way through the area it won't be a big deal, I've got the means to do so but it'd be a pain, Haha
