Slaughterwads - Anything we've missed?

[Da_maniaC]

So whenever i play DooM with a buddy of mine, we like to plough through some cool slaughterwads together in Coop mode (using ZDL).
But we may have come to a point that there are no new mappacks left to to play.

I'm not talking nuts.wad or anything but we really enjoy playing stuff like Sunder, Chillax, Combat Shock, Okuplok etc.
So anywhere between 1500-25.000 monster count but the maps are fairly cool as well (not just one big killbox).

Is there any wad out there we might not know about?

This is what we have played so far:

Slaughterfest 2011
Slaughterfest 2012
Slaughterfest 3
Slaughtermax
Sunder
Rush
Dimensions
Deus Vult I
Deus Vult II
Death in Excess (DiE)
New Gothic Movement 1
New Gothic Movement 2
Chillax
Combat Shock
Combat Shock 2
Disturbia
Speed of Doom (last 3 maps)
Toilet of the Gods
Very Hard (vhard.wad)
Invasion UAC
Drown in Blood
Holyhell
Tokecoop (that was never completely finished that i'm aware of)
Okuplok
Long days (a bit unplayable like nuts.wad)
ESP (no offense.... we really tried...there's just something about ToD's mapping style we really dislike)

Of course we also went through the classics:
Alien Vendetta
Hell Revealed 1
Hell Revealed 2 (progress wise this one is svery VERY confusing..so many small maps)
Scythe
Scythe2
ScytheX
Kamasutra

Some wads which were mentioned in slaughterwads topics here and on Doomworld which weren't really slaughterwads imo:
Grime
Italo Doom
Necropia 2010

Is there anything we may have missed out there? Please post all your true 'slaughterwad' suggestions!
We would really like to play more!
(not regular hard wads).
