If i may add to this thread..

Phil, STFU, and I played on the map and tested cading the vents with vending machines to see how difficult it was to get in. While they are on their sides, vending machines can be pulled out slowly, but with enough time to get to humans. IF HOWEVER the vending machine are on their front or back, they are impossible to pull out (within round time) as we had a match where the zombies were pulling on a vendy on its back for most of the roundtime until round end (it looked as if they could've gotten it out, but as i said there wasnt enough time.)

with how many vendies there are in that room available to plug the two holes into the area, it may be worth adding to the illegal cades list.
