sounds sorta like that survival thing they did in jersey a while back, they took like 10 people or so having different skill sets and left them to survive in an abandoned warehouse district in jersey that'd been cut off (fenced in really) from the rest of the area.
was pretty cool but then again i can't really it on authenticity since the invaders were quite obviously incredibly staged/timed.
still it was interesting to watch though, you realize it's not realistic pretty fast when the science skills guy (old man who almost resembles einstein) starts building all sorts of crazy tasing weapons and firethrowers though
