Questionable Ethics : Alpha test Left 4 Dead 2

Uploader: clipclop

Author: Nihilanth

This campaign is a sequel to 'Questionable Ethics'.
I strongly recommend playing 'Questionable Ethics' first.

(!) This campaign is long and difficult. Teamwork is crucial.
(!) This campaign could be confusing for L4D2 beginners or those who have not played 'Questionable ethics'.

The Concept and Story very great but the Map playing it at easy mode even there is extremely difficult and takes a lot of you. I felt my heart fast pumping all the time.

clipclop March 2022

"Fast pumping heart" is actually the exact response that I expected with the players.

VincentGR September 2020

Ok, this is a great map. Finished it with the team in 4 player coop mode. Great gameplay mechanics with a taste of portal.

PanosGR September 2020

Hello team fellow! ;)

ABSOLUTELY STUNNING

By PanosGR September 2020

This is among the best maps I ever played with my team. The action is intense, it has great graphics and it also needs some FPS skills since you have to climb on tube systems (and more) while the zombies keep on attacking! I recommend that you play Questionable Ethics in co-op with your friends instead of the, brainless at times, bots. Congrats to the creator! Try it! It's GREAT in every aspect!

clipclop March 2022

Thank you. I wanted to make a campaign in which almost every L4D skills are needed.

MikhailSV May 2020

The best! Now i wait a sequel more than Half-life 3!!!111oneoneone

Good map

Great

By mmavova December 2016

A bit long and hard (some weird puzzles, etc, I did not play the prequel). Very well made and fun to play. The part with jumping on pipes is weird (what are the cars and buses doing there??) and long, but it adds to the overall atmosphere.
