This acihievement is mainly having the right wepon, in the right place at the right time. The best way to do this is to let your friends run ahead of you so they wont shoot the infected, then using a bile bomb (jar of vomit), throw it on the floor and take a vantage point. let all the infected gather around the area of vomit, then fire a shot in the middle. With a bit of luck, you'll get it instantly.

For sure. Throw bile bombs at the same focal point and when enough gather, just shoot a grenade in there.

Ive gotten this twice, thanks to steam, what i did was go to the barns level of dark carnival, at the end throw out a bile and wait for the zombos to gather around it and blast em, thats also a great way to get fried piper

If you are playing by yourself, since the AI loves to shoot the zombies around a pipe bomb, in the tunnel of love there is a spot where you drop through a hole in the floor you should be able to shoot down there and get it w/o any bile or bombs, but if you have them it really helps. Also, at the end of The Barns (part 4 of Dark Carnival) you can hang out in the saferoom and a never-ending string of hoards will come after you, with a bile bomb it will be easy.

#8 is by far the easiest. You start out with the grenade launcher and bile a foot away from you. I did it with a second player so the AI would stay with them on the other side of the map so they didn't kill the zombies

Hmmm some of these are great ideas but I tried most of them but even with a second player the AI still kill some of the zombies....

Play with someone else and kill the remaining AI. The best place I found to do it was at the concert, use either a bile bomb or a pipe bomb but if you use the pipe bomb make sure you're quicker than the explosion. Theres a grenade launcher at the top of one of the towers, climb up there, throw your bomb, shoot the grenade launcher when there looks like theres enough zombies gathered around the bomb and just repeat until you get the achievement, it took me a few attempts.
