Well first off, I will talk about the disappointing campaign.  The campaign was fun and excellent but the very last mission was such a total disappointment, but overall it was great fun.  I truly got into the story and just in the battles was simply exciting.  Its just that last mission..ehh. The multiplayer is extremely fun and can be extremely irritating.  Most of the time I have more deaths than kills but its so fun you dont really care if you're terrible at it.  Its even more fun when you have a friend playing with you.  My friend and I had a blast camping in this one spot watching it side.  It is just pure joy.  Plus, zombies is back!  The zombies mode is still as fun as ever but now you can play as Kennedy & others!  Overall, great game.
