Nine Inch Heels

Took a quick look, only map29 looks like something spicy (At least as a recommendation for someone who punches cyberdemons like NIN) :P Trocket is a cool mapset tho

Also, there's Slaughterfest 3

Map 31 is something of a mini slaughter map. The enemy count is extremely dense given the incredibly cramped areas you have to move around. I was able to beat map 29 on UV, but map 31 is where I threw in the towel. As someone that doesn't particularly like or dislike slaughter maps, I thought map 29 was well designed for what it was. 

I always considered maps like MAP31 in Trocket as "congestion maps". But the term "slaughter map" is already loosely defined :P
