From my experience AW is worth the money. I like that it takes a new turn at the movement mechanics, but, like any other COD there are a variety of issues with it. The new Exo survival is an okay co-op and personally I love the new DLC and find their version of
Zombies is very tasteful! The guns are new and inventive and the exo suits encourage a new style of gameplay, both with it's each pro's and cons, but all in all I think it's a decent game from my playtime and very enjoyable.
