I'm in the market for a "screensaver" style map. I made one myself for Half Life Source, its a simple lab with computers that scientists walk around and "act busy" in spots and their AI allows them to talk to each other.
Not asking for a miracle, this can literally be a small office with a locked door, 2 scientists hunched over a computer, 1 walking back and forth and a barney by the door.
Just ask you make it look believable at least, wall decor, the like.
For completion, set the flags on 2 of 3 of the scientists to post-disaster; only one scientist will use pre-disaster questions/answers/comments.
