Iam hooked! On the new Call of duty game (world at war) you have a chance to unlock a cooperative game mode in which you fight zombies. However to unlock this you have to beat the game. My question though is: what strategy do you use when fighting the evil hordes of zombies? When I play I typically follow this pattern

1. Buy the cheapest gun ( the bolt action rifle) I like this gun because it delivers accurate and powerful headshots to most zombies.

2. After earning more money and keeping windows boarded I usually buy the second gun in the first area. I use The regular rifle as a second gun to my bolt action rifle because it shoots faster than the bolt action.

3. At about round five I normally open up the help door on the first floor to gain acces to both the thompson (which then replaces my regular rifle and becomes a primary weapon with the bolt action as a secondary) and the mystery box of which I use to try to gain acces to any type of machine gun and hopefully either a ray gun or a flamethrower.

4. After all this setup ifIam not able to obtain either a flamethrower or a ray gunI run with two machine guns. This is where I typically wait and survive while keeping as many windows as I can boarded up .

5. I have actually not reached level 20 yet, but I typically remain on the first floor only up until level 15.

6. When I reach level 15 I move the couch in the back "help" room, NOT the couch in the first area. This way if you get overwhelmed by zombies you can back into the corner with the grenade purchasing outline on the wall.

And this is where my survival story ends.

I want to know what happens in further levels and how many levels there are.

Anything special happen? any zombie boss battles? any zombie dogs? do you ever escape this twisted relic of a building?

The one thing I do want people to type though is the strategy you use for survival.
