in my professional zombie killing career, i belive that the MOON map is by far the very best map and the most fun solo or in a party...
solo= 8 (but had to turn off b4 i could die)
group 4 people= 18 ( had to get off b4 we could all finish AGAIN)
my solo stratagie
when u start knife all the zombies that u can b4 the alarm blares
get jug by throwing nades off the wall in the pack a punch room, and by shooting the train u made and rack up some big points. then when u have 2500 at least go into the teleporter room and buy jug (or speed cola if u prefer). when in the teleporter room run a small train if u can in there untill u can exit safely out of the room and back out into the field. then run one more circle around and go onto the teleporter. IF U HAVE ANY BULLETS LEFT SHOOT AT THE HORD AND IF DOGS COME KNIFE LIKE CRAZZZYYYY.
now go get a mask inside (of course) and kill all the zombies untill u have enough for quick revive. BUY THAT. then leave around round 3-5 or whenever u think u CANT pull it off. GO BUY THE M14. stay another round and leave out the olympia side of the map and go to the power. TURN ON POWER. by now u probably shouldnt have enough to go straight to the dome or out side. IF U FIND THE BOX CAMP BY IT UNTILL U GET A USEFULL GUN. now once u have enough money go to the dome or outside. RUN A NICE TRAIN. keep running trains untill u hit the box enough and get a good gun that u want to upgrade

.
now after u get the gun u want to upgrade and around 5000, warp to earth. take the gun B4 u upgrade it and go to earth with a crawler on the moon. at earth start a train and use the remaining ammo that u have in ur gun that u are going to upgrade and then pack a punch. then run another train around B4 u grab it and grab it on ur way around the second time then head back to earth. DO THIS EVERYTIME U GET A NEW WEAPON.
now head back and run trains and do the easter egg
