I didn't play very much of this one to be honest since survival isn't my thing in this game series. So to start this off it's the same as the first thing thing survival but with big improvements you get a cutscene in the beginning and choose what you want to do. I did practice mode and tried to see if you can kill the casier who has infinite health and kills you with a minigun if you shoot him a bunch of times. Pretty funny not gonna lie. You get a new survival mode which is Sentry Bomber Survival which has you fight robots that try to kill you when you get close to them. They only take your health when you are close to them. There are new weapons like the gauss rifle. Not gonna say much about the other modes since it's been in the first one of thing thing survival. I give this a 8 out of 10.
