This first tactic is best if you have 3-4 players. What you want to do first is get quick revive, but the trick does go after only three uses, so let the best player not have quick revive. Then when all of you have enough get the M14 (tip: on round 1 with the pistol shoot 3-4 times, then knife to get the max amount of points and then when you have the M14 shoot once then knife (only works on round 2)).

Now make sure that everyone has 2,200 points each, then you want to stay down stairs in the start room and by the bar (not the one with the quick revive behind). To the left there is a door, now take it in turns to unlock the doors.

What you want to do is get to the outside bit. Then get the gun on the wall (the AK-74-U (I think)). Get 1 each, then have 2-1 players (1 if you have 3 players) walking around the outside helping the others.

Have one person at the door which leads you and your co-op partners outside and the other at the door frame made of wood. Stay there for a few rounds.

Now what you want to do is make your way to the power switch, then you want to buy jugger-nog.

After that start looking for the random box. Then go to the stage and go round together and shoot at them - try to make a large train and spray them, but never ever split up!

Also when you have enough money link the teleporter and go to the pack a punch and pack a punch your weapons.
