In the campaign aspect? You'd need the help of google search or that one FAQ to get into some of the background detail but, the developers said that they made it so that you didn't have to play through the first game to get what's happening in this one.
NER , Oh how you haunt me. The server El Nido is called El Nino or El Ninorino in my book
well they said that they are trying to make this game easy for players who didnt play the first one.......and that reminds me, why are 85% of the people that I play conduit seem to be noobs these days? I mean, there are lots of lower ranks and people that barely know what they are doing. Who buys the conduit this late? I can only guess these people saw C2 and want to try the first one, thats all I can guess...
CONDUIT MASTA!, GOLDENEYE SLAYA!, AND BLACK OPS PLAYA!
