What can I say? It has a nice, short story mode, it's great if you have friends around, and the online is simply spot-on
SONY's Welcome Back programe really brought this game it's much-deserved attention, aswell as bringing a huge boost to the Virus cycle feature.
The main story cut down short kinda goes like this; You control either a male or a female character, who are immune to the Zombie virus, and must reach a lab to help cure it. You must get past everything that gets in your way, or you will not survive.
If you aren't that good at playing on your own, you can play a Co-op campaign with a friend, online or offline. I tried Co-op first, seeing that it if I died, I would have to restart at the last checkpoint. 10 minutes into the game, I was already addicted to the game, as was my friend(And he's an Xbox fan(!)). As we progressed, more weaponary and armour was available to use, such as SMGs, Shotguns, Molotovs etc.
Overall, this is a superb game. It has many suprises in store which will keep you coming back again and again.
