Looks Okay plays Okay but that is all it is OKAY..
The gameplay is pretty good and the fact you can buy the weapons of your choice and allowing to get more ammo which means that you do not have to find the ammo but you don't have any more ammo until next round or you stumble across the random ammo crate there.
I think that the game sounds are very good and when you shoot the guns have a sense of depth or feel to them so when you shoot the pistol it will give you a satisfying sound a recoil when shot.
The zombies on the game are not really very hard and they do not come in droves but if caught off guard you will die. The fact that you can weld the doors to stop them from coming in and you can heal yourself and other people. There are classes or perks as they are called inside of the game these level up allowing you to use better weapons.
The games graphics are also not very good but the gameplay and the game it self is pretty good. After a few hours you will start to get bored people do not talk but they will share money with you to allow for weapons
Plus -
Servers have a lot of people
Gritty graphics
Decent weapons
Realistic weapon feel
Cons-
Can be hard
Flashlight will only show up on one wall not dynamic
Different zombies but just as stupid.
