This is exactly how I got it. Even if it doesn't work, just start the campaign again on expert and ur sure to get it.

As Strikingstriker said above, Dead Air is a good way to get this. Another easy way to get this is to throw one when there is a horde after the rescue vehicle has been contacted. Here is a really easy way to get it.

Note: This is not my video, I take not credit for it.

Pyrotechnician - 20G (Original Achievement)

Difficulty: 1/10

As said above, simply start a game in Dead Air and grab a Pipe Bomb off the table. Walk over the the ledge and toss the Pipe Bomb straight down and watch the zombies flock to it. This may not always get 20 Zombies so another method is to wait until you get to an event. (I forgot the exact name but events are situations where you make a loud noise and a ton of zombies swarm you. ex. The hospital elevator, the dam bridge in Death Toll, any finale.

This is easily achieved by starting up the No Mercy campaign and beginning in the Subway. If you look around, you should be able to find a pipe-bomb. Press to equip the pipe-bomb, and once you see a large amount of Infected, toss it into the middle of them by pressing . The beeping from the pipe-bomb attracts the Infected, so it should draw a lot more after you throw it.

After you take a grenade with a timer, wait for a large stream of goiter to come at you, usually it is accompanied by music. Throw it in their direction and away so that the survivors do not shoot at the infected. A crowd will gather at the bomb and boom, your achievement.
