This game is much better than it's predecessor. The campaigns are much longer and harder to beat, even on normal. The addition of melee weapons were a huge plus and are very fun to use. The campaigns now play like a story, unlike the first one. Meaning the first Campaign "Dead Center" it's ending works it's way to the next campaign and it goes in order. The weapons are plentiful and useful and the new additions like fire bullets upgrade (Turns a mag of any gun into fire rounds) and a defibrillator (revives dead players) work wonders as well. The new special infected are great additions as well, their is even uncommon infected as well. And the new scavenge and survival modes are sure to add to the fun. Over all if you liked the first one or didn't even play the first one you will be very pleased with this one, worth the buy IMO.
