- What cons?
That thing has always bugged me! I'm glad there's actually a mod... FINALLY... to fix it. It's such a simple idea, but it does exactly what everyone has wanted to see be done for the longest time. If I could give more than a 10, I would.
-allows for easy access to any mutation without having to wait weeks for it to become available.
-numerous glitches, such as custom soundpacks not working in some mutations and the game just flat out freezing.
Overall, this is an awesome mod, but it does still need some work done.
+Feels like an actual L4D map
-None that I can think of
I cannot really think of anything wrong with this map. Maybe, like others have said, add a title card at the beginning of the campaign.
