(adsbygoogle = window.adsbygoogle || []).push({}); First of, this strategy is for 2 players. You can do 3 or 4 players, but I have found it works best with 2 players. I will provide a step-by-step tutorial on how to get to round 35+. This does work for definite, me and a friend got to round 41 when the host had a power failure in the middle of a round.

[multipage=Rounds 1 - 4]

For rounds 1 to 4 one player watches the windows downstairs and one watch the windows upstairs.

Round 1, just knife once. Round 2, just knife twice. Round 3. Put 8 shots of a pistol into each zombie, then knife twice. Round 4, put sixteen shots into a zombie, then knife once. At the end of round 4, the player with the most points open the door upstairs and each buy the MP5K of the wall for 1000 points.

[multipage=Rounds 5 - 7]

For rounds 5 - 7 camp at PhD Flopper and just kill every zombie with any spare ammo from your pistol and your MP5K. Buy ammo whenever you need, but only when you see a clear path to the ammo of the wall. At the end of round 7 keep a crawler and go open up the doors to the power switch, and to Juggernaut. Each get juggernaut, and hit the box once or twice. Kill the crawler and return to PhD Flopper.

[multipage=Rounds 8 - 9]

For rounds 8 - 9, just do the same thing you were doing before at the PhD Flopper machine, dont buy PhD Flopper though. If you go down your teammate needs to try and revive you, and at the end of a round keep a crawler, if you dont have Juggernaut, go and buy it. And hit the box once or twice. Also, use the lander at PhD Flopper then kill the crawler.

[multipage=Round 10]

For round 10 it should be a monkey round. Do whatever you normally would, defend Juggernaut and try not to let a monkey touch the Juggernaut machine. If they dont touch it then you will get a free perk, everyone reload before getting a max ammo.

[multipage=Rounds 11 - 13]

For rounds 11 - 13, just keep camping at PhD Flopper. At the end of every round you should keep a crawler to either get ammo, PaP guns, hit the box or get perks. On the end of round 13 keep a crawler and go and use all 3 lunar landers so that the PaP room can be opened. Go to the power room and activate the launch sequence. Now, we will start the main strategy, one player run around the box location outside the Pack A Punch room, up the mini hill thing, turn left to face the window and then jump down through the hole in the wall and start the loop again. And the other player runs around the room just outside the Pack A Punch room, the thing with the four legs is what I mean. If you cant decide who goes where, the player with the Thunder Gun should probably run around the box location as more zombies spawn there. If no one has the thunder gun, the player with the most ammo/best guns runs around the box location.

[multipage=Rounds 14 - 18]

Keep doing this strategy and whenever theres a monkey round go to the perks you have the you definitly need. Keep hitting the box till one player has a Thunder Gun and Ray Gun and the other player has a Ray Gun and RPK/HK21. Each player could do with Gersch Device and only throw it when some one is down. Once you have loads of zombies just use the Thunder Gun to save a lot of ammo.

[multipage=Rounds 19+]

By round 19 everyone should have the required weapons, the only perks you need are Juggernaut, Speed Cola and maybe Quick Revive. For monkey rounds one player go to each perk machine, Juggernaut and Speed Cola. If you run out of ammo use the Thunder Gun, or upgrade. If you have no ammo in upgraded weapons, go to the box and get rid of any gun apart from the Thunder Gun as you NEED the Thunder Gun. Hopefully you will be able to get to very high rounds.

If your having any problems add LMFAP09 and I will try and get to high rounds with you.

pretty good strategy mate

This is the same as most people run around in circles i class that as noobey

You know your more likely to get further with running around than just camping...

I dont camp i mess around i dont shoot much until i get a ray gun either i just buy phd flopper and dolfin dive off everything.

Ok then (too short)
