how is it compared to L4D 1 ? I am on the fence about buying it.
It's better? It has a new mode of play called Scavenge which is the sex... It basically is 4v4 with infected trying to stop the survivours from getting all the gas cans to get the hell outta dodge. Also more weapons and a Realism mode which I like... Also expert is HARD... Advanced is the equivalent of Expert from L4D which I also like. More maps and more weapons... I got it for 30 bux on Black friday.
