the staires is the best last stand point it does work but only if u have monkey bomb but u will need a better back up wepeon like a shotgun but yes i would work?

It works until about round 20. As when you go for the ammo with a monkey bomb there are too many zombies which aren't close enough to the monkey bomb when it goes off, so you get swarmed before you can get up the stairs.

good point legalos i just couldnt be arsed to try it myself 8) haha

This got us to level 28 with 4 players before I messed everything up.

This chunk if for level 20 and above when you have enough points to but everything and alot of luck for the guns.

So we found the best tactic so far is bowie knife area, on the stairway thing at the end where the mystery box appears.

You want everyone with:

All 4 perks.
Bowie Knife.
Monkey Bombs.
Bouncing Betties.

Try and get 4 frags all the time.

Now the four of you want a combination of:

Browning or MG's personal preference for it, I like the MG42 more.(Fully upgraded)

And one or two guys with a Wunderwaffe, also upgraded.

Then set up:

Ray's and WW at the back standing.

Ray's and Machine guns lying/crouching on the front.

Only move for Insta kill, Bombs and MAX AMMO!!.

Throw monkey bomb out the window and then once it gets a crowd frag it before it explodes, at high levels it just doesn't kill the crowd.

Ok so now you have the wave pouring in at you.

Its crucial you don't have more than two people reloading at most. Brownings take the longest time so call a few seconds before you do.
When the front two reload get the back two to unload near full auto ray guns at the zombies flooding in. If it goes haywire get a WW unleashed on the crowd it will stem it down considerably.

Obviously you have to improvise for yourself and your team. Just clear it and give warning before you do anything.

It would work only problem is Ammo costs like 4500 so hopefully you got enough money to buy it LOL

i thought you only had to pay 4500 once
even if you are right you probably would if you helped out on the stairs cus of the amount of the flippin things

oohh my goodness this actually worked i thought i was only gunna survive to round 15 doing this but i got to round 24 all of our teamate had the stg upgraded all the perks and 2 of us had monkey bombs the other guys had bettys and we all stood where the box apeears in the room with the bowie knife and just aim for the head and have a backup gun like a upgrade trench gun or double barel double barrel preferably it is stronger and if you have double tap and quick reload it shoots faster so yeah this works thanks for the post man.

we would have survived longer if out teamate didnt lagg and die then we all died.

I do that it works out ok but only till about 25 for me.
