This guide is going to be small; I basically got the Idea of it from another Guide owner to use this layout above (All credit to this Photo to his Guide). (Let's just say it worked) You must be patient when you are doing this. You won't get the achievement right away, it takes time. I'd estimate it took me around 2 hours to do, on occasions I seen the achievement pop way faster. It all really depends whether or not the Zombies want to be lined up in a row or not.


The steps below were provided by my “Inspiration” to make this Guide.
ROUND 1-4: Stall, until you have a lot of money to buy a Sniper Rifle.
ROUND 4-6: You will get ammo, so you won't need to buy any. Just save your money.
ROUND 6-?: Buy barricades. Wooden or Steel. But put it in the layout above and wait until the right amount pops up and then "POP" them with the Sniper. You should get the achievement.
