Although I am 11, S RJ WHANIE from x-box live said I was a pro for sticking up for them, and taking all the zombies out.
My method to Five on Zombies:
1.) Use up all your pistol bullets, without buying a M14 or a Olympia!
2.) Open the doors and buy the MPL.
3.) Tell your friends to get to the elevator, guard them!
4.) Run through, shooting the zombies.
5.) Firstly, shoot their heads off!
6.) Then go for the bodies!
