Yes, I would like to second that.
There are some insanely excellent entries!
The real winners are everyone that plays this game.
I would hope the good folks at Tripwire Interactive package the winners up and push them out as a map pack.
(I've not heard anything about whether this is a true statement or not, but I would hope so.)
In any event, good luck to ALL who've entered!
