Wads where the objective is to be stealthy?

I've been going through wads that I don't want to commit a lot of time to by using the mdk/one hit kill command on enemies, and since I've been sneaking up on them, I thought hey, maybe there's a wad where the objective is to one hit kill them or somesuch before they have a chance to alert other enemies?

enjay made a level in the early 2000s based on the game Thief, you could try that (sorry I'm not sure of the wad's name)

There's Doom 2 Reloaded MAP18, but only the first part, and the objective is not to attack at all during that time.

I'm guessing it was this Heretic wad you're talking about.

I sorta designed a lot of Project Einherjar maps so that utilizing sneaky tactics was beneficial. Map03 and Map06 come to mind: they both feature sprawling offices where one sound alerts everybody in the area, and they all come gunning for you from all directions. Same goes for all of Map18, which is a huge city.

Nex Credo's map10/Freedoom's map31. You fire your gun even once in the map, and the Cyberdemons awaken.

Tom19 map01 might be worth checking out if you are into stealth 

Evil Eye teaches you to mind your manners whenever in its presence, otherwise it'll simply make you dead.

Doom 2 reloaded map 18 warehouse siege. Already mentioned I see, thx slow phone. I liked it despite I'm not a fan of stealth games because the switch can be deactivated and the monsters killed

Just found out Blade of Agony Episode 2 starts off with a stealth level, but I'm also told it sucks, so try at your own risk.
