Necrobrood is a three map pack with new monsters, textures and skins. The theme follows on from Permutations of the Rotten with a very dark and morbid metal style using grotty brownish modified ID textures. A traditional Quake style but with a unique hand. A number of much stronger opponents with upgrades and improved AI to the Grunts, Enforcers, Ogres, Hell Knights and Shambler. You've been caught by Quake's minions and caged awaiting your death, now it's time to escape this hellish Quake prison before you rot. Find your way to the surface and destroy the Quake god.
