Left 4 Dead 2

Left 4 Dead 2 Achievements


Kill one of each Uncommon Infected.   

There are several Uncommon Infected dotted throughout the different campaigns. You may not notice them while playing but they are all level specific.

  • Hazmat Infected
  • Mud Men
  • Clown Infected
  • Worker Infected

You will probably earn this achievement without even knowing so just play through the campaigns and watch out for the different types of Infected.

I read somewhere you have to kill all five. This is wrong, I got it before I killed the Riot Infected (The Parish), when I had killed the other 4. But here is a full list with the campaign.

Hazmat Suit/CEDA (Dead Center)
Clown (Dark Carnival)
Mudmen (Swamp Fever)
Construction Worker (Hard Rain)
Riot Infected (The Parish)

This is harder to get than you'd think :/ You have to kill a witch, a charger, a hunter, a smoker, a boomer, a tank, a spitter and a jockey.. just to get the achievement. Not al of them are needed for the achievement but nobody seems to know which of them is the FOUR required..

For those of you checking, I think KryptosFang is correct. I got the achievement as soon as I killed the construction worker. I certainly haven't killed a Tank or a Witch. Witches, hunters, chargers, spitters, tanks, smokers, boomers, and jockeys are special infected I believe, not uncommon infected. I'm not sure which one of the five you don't need in order to get this achievement.
