i agree dark, addicting like none other, once you start with teh c-packs, there's no going back.....ever....they replace the medpacks.
actually i played a game like that once, was uber fun, drop armory, ip arms lab research cat pack right away, whenever someone calls for meds i say "SCRew YOU WUSS! TAKE CATS INSTEAD! BBSSSSHSHSHSHSHSHH!!!" the response of course "where can i get more!" then "only the first one's free...."
