What are the best Left 4 Dead custom maps?

I want to try custom maps/campaigns. Which are the best and most popular ones in your opinion. Not looking for survival maps. I know the best site for them already so need to tell me that.

Me too. I want to buy the game soon and so want to know something about it. Is it worth it?

I've played all of these and i would recommend them.

Death aboard, Night Terror, Vienna Calling, Suicide Blitz, Coal'd Blood, Dead Before Dawn, Back to School, Heaven Can wait.

If you want to check out more go to l4dmaps.com

My favorite is Death Aboard. Some other great ones I have played are Night Terror, Suicide Blitz, and Dam It. All of these are just as good as any of the Valve made campaigns.

L4Dmaps.com has a good rating system that lets you search by the highest rated. This will give you a good idea which ones the fans like the most.
