Need some Megawads

[Haloless0320]

Someone start naming good megawads...anything between 15 and 32 levels.

[Death-Destiny]

I feel like we've been through this already, but anyway, here's some of my favorites:

-Hell Revealed 1 and 2
-Memento Mori 1 and 2
-Scythe 1 and 2
-Alien Vendetta
-Requium
-Kama Sutra
-Deus Vult II
-Equinox
-Congestion 1024
-Icarus: Alien Vanguard
-Rebirth
-Revolution!
-CChest 1, 2, and 3
-1 Monster MegaWAD
-2002: A Doom Odyssey
-Zpack

That should get you a good start! =)
(I know DVII and Equinox only have 13 maps. So sue me.)

There are others famous one (depending on your taste) :

Batman Doom
Eternal Doom
Demonfear
Strain

Marswar is a fun, old-school Megawad.
