Questionable Ethics Left 4 Dead 2

Uploader: clipclop

Author: Nihilanth

Survivors got stuck in a mysterious research facility.
This campaign is about randomness and some traps.
I started making this campaign out of curiosity.
But as it progresses, it's got bigger and bigger.
Have fun. 

(!) This campaign is long and difficult. Teamwork is crucial.
(!) Custum models for weapons, modified server are not recommended.
