...And I've checked the Wiki and they don't appear have this particular danger room template on record:

OOO went Hardcore on this one :P. Four T3 Puppies respawners on spikes, surrounded by ghost blocks. Very cheeky and very nice and unexpected. Oddly enough, my Irontech destroyer that I brought actually ended up having more use than my Nitro because OF its smaller radius. As well as my Volcanic Pepperbox.
Anyone else seen this.
I've seen this before back when the danger rooms were redone (months ago). Its actually easier than it looks :) Hug the perimeter.
