Questionable Ethics
Left 4 Dead 2
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 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.

It seems so strange that I've encountered the same password on this map 6 times. I've never played the map for 1000 or more times. It's a special number that is linked to some not-so-widely-known event. There might be also other numbers that I failed to notice because they're meaningless to me. Is it so that the author did pick a limited set of passwords, instead of using totally random numbers which would have 9*8*7*6 combinations, or is it so that rate of appearance of some special passwords was intentionally increased? If anyone knows that, please tell me. I won't tell those people that are sensitive to the number. I just want to make sure that the world is real, or it did give me enough sense of realism.

My team mates always want to play this Campaign, lively, balanced and very interesting with a few surprises along the way. Fantastic job!

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