Note from author
pl_dustbowl started as a joke, to prove my point that goldrush is dustbowl v2. but seeing as everyone loves it and its a blast to play. i thought everyone else would like to play it. if you like this map please check out cp_dock2 as well as some maps for portal that i have made.

Credit
I will not take any credit for pl_dustbowl, valve software should get all the credit for this map. I have and never will consider pl_dustbowl one of my maps.
