"This is on Shrak. If you really are Team Shambler, you’d know that this map was created during the early stages of development for the undersung shooter of the late 90s, but was sadly scrapped due to sexual content." 

> I will even make an entire playlist dedicated to all of the Shrak maps you made which were cut from the final product. A lot of great maps to be shown, it is my duty to make them public now. Don’t worry, I will give you proper credit there and tag you so the world can see what never came to be :)

I think the guy will play other custom made maps in Shrak and present whole bunch of such 'cut levels'. It's his duty. 

I hadn't seen that yet. Guy is proper mentally defectively OneMadGypsy style meltdown fodder. Or a semi-amusing troll pretending to be that demented. 

here he goes loading another custom made level in Shrak and this time claiming it's another LOST LEVEL by...... TEAM SHAMBLER :D

I cant find this map on Quaddicted, was it a part of some jam? 

It's SM189. 

That tells me all I need to know.
