It's like, up the stairs. And then up the stairs again. It's not rocket science!
It's also completely hilariously easy to kill stuff with the ED-E, Boone and a sniper rifle of your own. Combine it with good draw distance, good gun skill and that thing that perk that makes sneak crits hit harder, and the entire outdoors is a line of dead stuff that used to be lit up in red. I walked through a bunch of deathclaws without breaking a sweat.
Also, is there some way to figure out a lot of Mr. House's backstory without working for the guy? I just walked right into his chamber and murdered him, it felt a bit too easy. There was an alarm and shit, but the robots didn't react, and I didn't even have to break out my maxed science skill. So I now have *spoler* a dead semi-ghoul in a box and a robot army of my own *spoler* without really knowing why. I mean, most of the stuff I know about the guy comes from the loading screens.
