Some dogs explode when they die, this does not hurt you.

With 4 players, camp near the box, wherever it goes. You can’t camp easily with 1 player, but it is the only way with 4.

With 4 players, the dogs come every 5 rounds usually (5/10/15/20 et cetera). This is different for less players.

You can activate the ? box, run and grab a perk cola and then get the gun from the ? box that you paid for and you shaould have 3 gunslots now (repeat at next perk when the box moves). You can ‘down’ yourself which gets rid of the perk(s) but lets you keep your guns (when you are revived) so you can repeat this. Similar to the betty glitch from the asylum.

rounds 1-3

Let the zombies in and stab them. You get more points for stabbing, plus rebuilding windows, and if you are lucky you may get a 2x points too.

rounds 4-5

open the wall, NOT THE STAIRS. Go downstairs and stay in the area at the bottom of the stairs. Use your points on box tries, to try and get an MG42 or Browning to help you through the dogs. Don’t worry about ammo, you get a max ammo at the end of every dogs round at the minimum.

rounds 6-13 (in order of importance)

buy bouncing betties. Fill the room at the bottom of the stairs with them. Do this every round (except dogs). If you need to reload, fall back to behind your wall of betties and reload. They will catch that stray zombie that might get you. If its a dogs round go to the narrow hallway to the left, behind where the 1st box is, and lay your betties in a line going outward, spread out enough that one dog doesnt set off more than 1 betty. Dont shoot at the dogs until all the betties are gone.

buy a thompson off the wall right across from where the first box is, and use that as your primary weapon, unless you got 2 weapons from the box that are better. It has good take down power, and you can buy more ammo for it anytime if you are in a pinch.

Stockpile points, and resist the urge to run out and defend the new box position. NEVER OPEN THE COMM ROOM. This strategy depends on not having to watch your back, and if you open the comm room door, you screw yourself. Most of the zombies will come right at you in a straight line, down the very long straighaway as you look towards the far stairs (not the stairs you are staying under). A few will come through the left window where you camp out for dogs rounds, and even less will come from the right side doorway from the window in the adjacent room. In this position, you have a viable choke point for the masses of zombies, and they have a long straightaway to run toward you, where you have lots of time to take them down with headshots through the whole group.

Never camp by the box, it is much easier to stay in your defensible position, and create a crawler near the end of each round either with a well placed grenade or by shooting a zombie in the legs with the ray gun. Then, only when you have a crawler, you can go out and open the huts and buy the perks you want. Juggernaut, Quick Revive, and Speed Cola are extremely important, more so even than extra box tries. Double Tap is a worthless waste of ammo, and you can’t afford to waste ammo in later rounds. Only once you have the 3 good perks, you should do more box tries until the box moves to doctors quarters.

Rounds 14-20

By this time, points will not be hard to come across. Stay the course with your spot at the bottom of the stairs with NEVER OPENING COMM ROOM. If the box moves to comm room, you are shit out of luck and hopefully you have a weapons set you are happy with. The Thompson is right there to buy and is a great weapon if you have Speed Cola.

If the box moves to doctors quarters, get a stockpile of about 10,000 points, get a slow crawler at the end of a round (you should always try for a crawler), intentionally down yourself with a grenade, have a teammate revive you, then do the 3rd weapon glitch with the perk and box at doctors quarters, then buy all your other perks back. If the box gives you a shit 3rd weapon, take it, then get your perks, then use remaining money on more tries for a better weapon. If you get run down to 1200 points and still have no good 3rd gun, just go back and buy the thompson, and stockpile more points for a try at the next round.

rounds 21 – xx

By now you should have good weapons and all the perks. The #1 weapons to have are the MG42, ray gun, PPSH, Browning, Thompson, and WunderWaffle, in that order. The waffle is good for groups, but has limited ammo and is a terrible primary weapon. Its good for clearing a room to revive someone, and thats it.

Keep laying those betties, keep fire on the choke points, and communicate if your choke point is getting overwhelmed or if you need to reload.

I made it to level 25 with me and my brother doing this, and Id bet that 3 or 4 players could go much much farther. We never even got downed for the first time until 22, when we had a bad sequence of reloads. I went apeshit with my MG and quick revive saved our asses, as well as my bro with his ray gun covering the door while i revived him. We made a crawler and he bought all his perks back easy.

The more specific strategy was this: One of us watched the main, straight hallway and picked up the occasional zombie from the left window hallway, and the other stood back watching the right doorway and covering reloads for the primary player. We traded positions every 1000 points, so we could both get some of the action and be able to afford things.

Good hunting!!!
