E2M8: The Portals of Chaos (Heretic)

Walkthrough:

This is one huge open outdoor arena. To start with, just go around clearing the area of beasties. DO NOT go up the stairs yet. You are going to be introduced to a new monster, the boss of this episode, and he is one badass. If you step up onto the platform in the golem area a wall section will open behind the rock shield.

Secret 1: Quickly cross the sludge and get the goodies. Believe me, you're going to need that enchanted shield!

There's another rock wall with an open area behind it across from the stairs to the east. As soon as you step inside, a series of crushers will activate. Stay to the east side and make a run for it.

Secret 2: Get the goodies then 'use' the wall section with the trident motif.

Take out the sorcerer and go through the teleporter. You'll have a couple of more sorcerers to deal with. Take them out and head for the stairs. SAVE THE GAME and head up the stairs. Get the mystic urn. You should hear a bellowing and see something huge coming towards you. This is the maulotaur, and as I said before he is a badass.

The best weapon to use against him is the powered up firemace. The huge spheres are absolutely devastating. Just keep pouring it on. If you need to get away you can use the teleporters. Once he's dead, the other portals will open up which are all exits from the level and the end of this episode.
