This instructable will hopefully help you get far in "5". It gives you instructions round by round and this stratagy has gotten me to round 17. So.... Lets get started!

Step 1: Round 1

Alright.... round 1... start by running over to the open alcove and buy quick revive, because as everyone knows: you dont have quick revive... YOU DIE! Once youvebought QR you want to break ALL the glass windows and then start repairing them... this will get you some much needed points. Let zombies rip apart your barriers and let them come in. Shoot them 6 times in the leg then knife them. this will get you the most points possibe for round 1

Step 2: Round 2,3,4, 5,6,7 and 8

at the begining of round 2 you should still have your QR. save up your money until you have about...... 4500 points.( this should be about round 5 or so) now open the other door on the opposit side, ( you shouldnt have bought any other guns or opened any doors) buy the MPL ( yes it sucks but it will get you lots of points if you spray into a herd of zombies) and open the elevator. wait until you see at least 4 zombies come charging through the door, then HOP IN and go down to the 2nd floor. Go down and clear ALL of the debries ( you should have the MPL and the M1911) now just walk in a circle around the 2nd floor and just shoot all the zombies with your MPL and make crawlers with your grenades. Now, once you have enough money buy the STAKEOUT and it should be a 1 or 2 shot kill gun for a couple of rounds. make 2 crawlers then go down too the 3rd floor, and turn on the power. now keep jumping through the teleporter untill it gets you back to the 2nd floor. walk around in the circle again and just save up untill you have 5000 points. now make a crawler and start activatingg the defcon switches. then jump through the teleporter and it will take you to the PACK A PUNCH room. upgrade your STAKEOUT and just save a lot and keep buying your STAKEOUT ammo. now go downstairs when you have at least 2000. look in through the windows and try to find the Mystery box. keep trying the MB until you get the ray gun

Step 3: Well Now You Know What 2 Do!

Well, you need to save up and upgrade your raygun in the PAP room..... keep running in that circle on the 2nd foor! you dont need me anymore. HAVE FUN! AND TELL ME IN THE COMMENTS BELOW IF IT WORKED FOR YOU OR NOT!

i will be coming out with a couple more stratagies.
