Right now I'm going to say I hate it even though I don't have it. Only reason I hate it is because people on my friends list won't stop inviting me to play with them I mean damn I get invited about 30 times a day and it makes me want to kill whoever put that option in the game.
personally i really dont like it . partially because i have no time to play it because of WaW clan matches and i dont really like unrealistic games, thats why im abit unsure about the zombie mode in WaW so im not really into the whole weird creatures from underground overthrowing earth idea
