I heard there were coming custom maps? Or maybe it was a hack on demo or something.
But is this something we can expect in the future? Opensource maps, etc?
I heard a rumor about custom maps?
Re: I heard a rumor about custom maps?
The development kit for L4D hasn't been released yet. Once that is out you will see a lot of custom content. I only know of a workaround to be able to play the other 2 campaigns in versus mode at the moment.
