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.

I wish i discover this map sooner in my life cause its really fun and very VERY UNIQUE My friends and i made a video playthrough XD.Sadly i cant post the link here but u guys can search AlexTV on YT

loocoomatuu December 2021

I like this map. We literally are laboratory rats xD

Shouto1 November 2021

I just beaten one of THE HARDEST Custom Campaign that I've ever played today on EXPERT mode with just the hopeless bots as my team mates in less than 6 hrs. 51 mins with 56 restarts but I died 61 times according to my gameplay stat that was shown to me but whateves. Anyways, love the level design and everything them traps really spice things up with this map and those traps got me killed a lot and made me restart like 56 times but overall its was one of the most enjoyable, challenging, long and tiring L4D2 Adventure I ever played so far in this website. So thanks to the author for testing my limits and patients with this map. xD

clipclop March 2022

Wow, I can only imagine 56 restarts. Maybe I made it too difficult. I am glad you had fun though :)

NeoTM July 2021

I run a heavily modded server and this map is running fine if you can play with people who are pretty good. Beside of that this map is really fun to play and it's a must have for people who love to think a bit and struglle a lot.

JeySieGee May 2021

This is a shocking experience map for my friend and me.

Challenging map

By HoLeung161118 July 2019

the traps are cattish.But I am greatly motivated by them.

Perfect

By kantagara April 2018

I agree with daywalkerdave1963, one of the best campaigns I've downloaded. Challenging, interesting, got something new in the game. 10/10 recommended.
