    This is done on the "Dead Center" campaign: Chapter 2

    The easiest place to collect these is when you have to get the Cola for the GunShop owner. Instead of giving him the Cola, sit outside the store and just wait for the CEDA agents (they wear blue or yellow HAZMAT suits) to come along with the packs and packs of zombies that will pour out. You should get a CEDA agent every other crew of undead that come out looking for you; if you're lucky you will get one from every horde that comes out.

    You should have the achievement in about 15-20minutes of opening the door, if not wait a little longer and it will be yours.

    NOTE:This is best done on easy, no need trying to be a hero. Also if you don't see many vials don't worry, the game director is all random. It might bring 10 vials in a row or it might not bring any.

    Tanelorn82In more than 30 minutes of playing this campaign and killing tons of CEDA agent, I only got 2 ... viles... and they were at the same time. The game isn't cool to me. But I know this solution makes sense, it must be a very good place to get it... normally.

    DarkSovereignXI got the first 4 in about 30 mins, doing this method. I then went into the back of the store near the coke, crouched, let my team kill them all got 7 viles in 10 minutes.

    This achievement must be done in the Dead Center campaign. Occasionally you will come across CEDA agents (men in big green / yellow suits). After you kill them, sometimes they will drop a vile of Boomer vomit. Do this 10 times and the achievement is yours.

    Note: You do not have to be the one to kill the CEDA agents. If a teammate kills them, picking up the vile still counts.

    Shock O RamaIt's a hit or miss. Sometimes they drop it, sometimes they don't. If they have it, you'll see it on their belt while they're walking around. Same with the nightsticks on the SWAT infected.

    JediJohnny7Edit your solution: you're totally wrong. you do not have to kill the CEDA agents yourself for it to count towards the achievement. I tried it, and it added towards my 10.

    QuarantaneYeah, you can see the guys carrying the vial.

    Also I would like to not that they are not always in green suits, sometimes they are yellow.

    And I also found this to be easiest on the first chapter as for me it seemed there were more of them in this chapter than any other.

    Nice guide though, positive vote.

    I actually just found a way to idle this on accident. Not that it's really needed. I was doing as solutions stated above, Dead Center - Chapter 2 (Streets). Play up to when you have to retrieve the cola, open the store door, but don't go in, just stand outside and kill the waves of zombies, group with your AI, and they will protect you. I was playing Campaign, instead of Singleplayer, so when I paused to go do something else, I was expecting to come back dead, but my health was still in green, and saw like 5 Boomer Bile containers lying around on the ground, I went around and picked one up, threw it, and picked up the next, etc. I went to check my achievement progress and I had went from 0/10 to 5/10 during the 10 min. period I was gone. Then I healed myself, and idled the rest.
