-It's a massacre
-The floor breaking and the first charger(wall breaking) were very good

-Everything except the tower has bad textures
-No depth of field at all
-Endless hordes
-Everyone was triggering the hordes,even the special infected themselves
-Witches spawning in front of you
-Inch-deep water making players running slowly(really?)
-Bot nav is terrible.We had to kill them every time there was a safe room
-Too open areas and no safe spot
-Extremely buggy
-It crashes a lot.
-Too short

I can not find anything worth playing this campaign for,as it is now and I recommend skipping it until it gets done.
It may has some potential but right now,it is something you will probably want to forget.
