One of the Developers actually did it save for the one radroach.
wow, that must have taken a few stimpaks... but when *SPOILER*
Spoiler there's the part where you escort some scientists from a lab to a big project, and when you get to the door the main guy says, "we can't go in until it's safe"
-- what can you do then? You have to 'check them out' as the helicopter guy says in Apocalypse Now, just prior to firing a missile at the problem.
Or at--
-- they won't open the door 'til it's safe, so you can't get info you need. If you don't already know the story, you're stuck.
By the way, having a follower do your killin' for you is pretty much the same as having your Shotty do the killin', IMO.
