Hey there!

Okey, this is by far the hardest damn achievement in this game. In order to do this properly we need 4 good players. So anyone out there who is missing this achievement and wants to get it. You are more than welcome to join and help each other out.


Survive an entire campaign with no Survivors taking damage from Special Infected. This doesn't work if you restart a certain map! You must complete an entire campaign all in one go!

You will need 4 good players total for this probably. (Most efficient) and play Easy. Play any campaign, one that you all want to practice. I believe Blood Harvest or No Mercy to be easiest.

Rush, and move swiftly, whilst staying close together, especially when Hunters, Smokers, and Tanks are nearby.
Spam melee when Hunters and Smokers are nearby to hit the hunter or your ally to release them quick enough to avoid damage.

Smokers grabbing you, will not do damage until he is next to you or traps you against an object.

Hunters don't do damage until a little bit after they pounce you.

Boomers can ONLY damage you by melee which doesn't happen often. NORMAL INFECTED DAMAGE AFTER BEING VOMITED/EXPLODED ONTO DOES NOT COUNT.

Tanks damage you by melee or thrown objects. Kill them by everyone shooting him quickly. Molotovs help. Make sure to use pipebombs and molotovs to keep INFECTED AWAY or else they will flank you and trap you so the tank will hit you.

Witches don't count. Not to mention if you go idle in game you have to start all over again. So there is no time to pee!
