Last night 2 friends and I tested out a camping spot at the top of the large spiral staircase (without having opened the door at the top). It presents a pretty good vantage point over the zombies, causing them to have to funnel through one small door and because of the stairs leading down we had room to back up if necessary. In the natural evolution of trying out this spot, we got brazen and decided to use nothing but sporks and tomahawks. To our surprise, it worked phenomenally well.
All 3 of us crouched and blocked the doorway, preventing any zombies from getting past us. The white player went in the middle so the zombies wouldn't pay too much attention to their flanks. Then we proceeded to spork the crap out of them. We were essentially working as a team to create a perfectly funneled spork meat grinder and the craziest part about it was that it actually worked all the way to round 34.
Once in a while, they would break through and one or two would get behind us. That's when the vitriolic withering came in to play. A couple shots from that restored order and put us back in formation. We weren't stressed about max ammos because the only time we used any was to put down the warden. It only took two seconds to do so because of the funnel.
I thought I would share this because it was fun, not a glitch, and unique to this map only due to the spork. It makes for some gloriously chaotic camping when you get overrun, ending with a light show of blue tomahawk flashes, claymore explosions, and green acid bursts dancing out of the screen like a 4th of July fireworks show! Have fun!
