So WTF do you want MERC, you wanna kill zombies without your flesh being draped out of your bootstrap well then listen here MERC.
Alright so where to start oh round 1-5 (This is gonna be very general strategy techniques until rounds 12 and up where the details willl be mentioned.)

1-5= Hold the lobby get as much points as possible by pistol shots and knife kills until the dogs.

Dogs- Head to Mp40 room get your gun of choice Mp40 preffered.

7-9- you can either hold the mp40 room or head to the stage rack up points as you please.
Mp40 room- 2 people guard the up stairs while to guard the down stairs windows.
if on stage- have 3 people on the mystery box spawn to lead the zombies in a line towards you (never go ont he opposite side of the stage while doing this) one person on the back window he can swap when he needs points.

10 and up- you can choose to stay on the stage for as long as you want at this point to earn massive cash, but dogs at this level will be a large problem if only equipped with minor weapons such as mp40s, galils, augs. if ray guns and thundergun is present in your party you should be fine otherwise get the power on, get juggernog etcetc.

Details on your success- after you have opened up the whole loop your team can start to take there positions. this involves one person looping zombies around in a single room, everyone will be doing this.
These are areas where you can perform the loops
1.The back of and on the stage
2.In front of the stage
3.The Lobby
4.the mp40 room with speed cola
One person of the team should be situated in each of these rooms and chorral the zombies into a group. Then by systematically killing off the zombies will cause them to spawn in the other rooms.
-Be sure to alert teammates that you are killing zombies to let them know that they are about to spawn in there proximity.
-by having the team spread out will evenly distribute the zombies and it is posssible that one person can collect all of the zombies and no more will spawn until he kills some which will disperse them amongst the rooms,
Corralling the zombies provides maximum bullet penetration resulting in large point increases, this also prevents unwanted spawning of zombies until the zombies that are under the teams control are killed.

!!!!!!!!!! If someone happens to go down they should alert the team as to which way the zombies are going so that maneuvers can be taken to reach the downed MERC,once revived then proceed to do the whole lap around the house until you arrive at your designated position.

another technique is if a person has a majority of the zombies and someone goes down he should NOT kill any of them until the downed person is up and he and the revivalist are in there desired positions to expect zombie spawning. good luck and eventully mobbing up the zombies and using the traps will be the only method to eliminate zombies from there on its up to you........... MERC.
