I mean, yeah, or in the Institute/Brotherhood

The Institute doesn't really have a security force, do they? I guess there's those Gen 2s standing guard, and I suppose the Synth Retention Bureau could work as one in a pinch...

It's not quite clear just how big the Institute is supposed to be (canon-wise). Everything is compressed, of course, due to gameplay restrictions, but I still can't imagine that they're supposed to be more than a hundred-or-so (if that) strong. More likely less. The whole point of inventing the synth was to give them a source of raw labor, which they wouldn't need if they had a bunch of extra people around. (even if they're all descended from the C.I.T. eggheads, somebody would have to fall to the bottom of the bell-curve)

Why isn´t this in the F04 build index/archive?

Don't know if you have far harbor, but the traps would be quite cool for this build.
