The Monsters of Enemy Mountain
Enemy Mountain houses a wide variety of demons and zombies which are keen to feast on human creatures. Most of them are the cast from regular Doom 3 but there are a number of additional foes that you will face, including several that were seen in Doom 1 and 2 but not in Doom 3, e.g. the Spider Mastermind and the Baron of Hell.
The monsters in Enemy Mountain have been trained to feast on human flesh and to attack humans on sight. However, they are typically very trigger-happy and, if provoked by friendly fire, will often start fighting amongst themselves.
The Cells Complex, where humans are taken after they are captured, is guarded mainly by the weaker monsters but as you progress towards the main headquarters from which you can make your escape, you will increasingly encounter some of the really badass monsters.
