Hi. I started a new game (got quite a way but then wanted to start over), and I'm back at the REPCON Test Site.
I found the manager's room, with the admin terminal in it, which gives you a ote about a safe in the old generator room with the password 'R3PCON'. But I can't find this room, or the safe, anywhere!
Please can someone tell me where it is?

No one's found it or it doesn't exist.

Ah, that would explain it.
I think the 'old generator room' is the 'stealthboy room' where you find the ghoul, right down in the basemant. There are loads of containers, and a generator, which hold to the note's description. I even think I know where it should be - in a large group of the yellow cargo containers, there is a table, which would be just the right size for a safe.

This is the reason I hate unmarked quests. You never know if it's actually there or if it's just you being thick.

Isn't that referring to the room with the Plasma Rifle in it. That is behind the 100 lockpick door (or 100 Science Terminal) but also you can drop in from the floor above. Hope were talking about the same building. REPCON Headquarters where you find the 2 Paladin BOS on the Top Floor.

He said the test site, which is the one west of Novac.
