I only played it one time.
I didn't know how to play and I was on survivors team. We were running through stuff and something grabbed me with a tentacle or something and I asked for help but they just kept going and started yelling at me in a language I couldn't understand then vote kicked me.
The Dead Money Addon for FO:NV is really great. Rather creepy and I find myself scrounging for every Stimpak like I used to do in the very beginning *g*
