Left 4 Dead 2

I used the prompt "A poem for Left 4 Dead 2 about zombies and dognose"

I'm pretty sure almost of all don't have this achievement from playing Left 4 Dead 2 Fifty three thousand five hundred ninety nine zombies killed! Z-GENOCIDEST 2: EPISODE 2 Kill 53,599 infected. You made sure the dead won't rise anymore!
