Looking for an OLD Doom wad that was VERY HARD

Okay, way back when I first started playing Doom my dad found this wad that was really awesome.

It was the entire first episode, the levels themselves didn't change except there were about 1000 monsters per level. It was INSANE. We went through playing co-op and it was a blast.

Can anyone tell me the name of this wad?

The name doesn't ring a bell... I swear I'd recognize it if I heard it. I'll have to check out nasty.wad but I'd like to hear more suggestions. I'm 99% sure that's not the one. :(

Dminator... That could be it! Last night in bed I kept thinking "Terminator? No!"

That just may be it... I'll have to check it out when I get home. Thanks!

That's a great wad, but it doesn't really fit the description.

What about UacDead? Thats a good old level.

No way does UACDead fit that description.
