Left For Dead 2 Questionable Ethics Campaign Walkthrough
Questionable Ethics is a downloadable campaign for both Left 4 Dead and Left 4 Dead 2 that implements many interesting puzzles and obstacles into the game that do not exist in the default campaigns. Questionable Ethics is one of the most innovative and original Left 4 Dead custom campaigns, and a sequel, Alpha Test, is currently under development. I would strongly encourage you to download and play Questionable Ethics with a friend or group of friends before watching the videos included in this walkthrough, as plaything the campaign for the first time without knowing what lies ahead is the best part of Questionable Ethics, as you will never expect what you'll see while playing.
This walkthrough shows that the entire campaign is playable with only two people, even though four people would make Questionable Ethics a lot more fun and a lot easier to complete. The bots are not very smart, due to the innovative puzzles that you face, and so you will probably see them killing themselves on multiple occasions during the campaign. Make sure that you have at least one other person with you to play this campaign, because playing it alone is next to impossible to do. My overall favorite part of Questionable Ethics? The cars, by far.
