I did and it freaking lags like hell.
Wait front of the shop door first when there's like 40 monsters left or something, 'cuz you couldn't go in at all. lol
I ACTUALLY had a game where people knew how to walk in and out so all 60 of us got restock and all O.o fucked up really!
What about, how many fuckin shots the mutants take before they die! SHEESH! I had 8 sirens after me at one point and they had me sorrounded :Y SO kamikaze with 3 nades on myself was the funniest.
