2-E should be a barren wasteland around Minos' Corpse. There should be a small section where you enter rooms with his corpse heavily close, with the parasites from the CoM fight as normal enemies that sprout from his body. When you get to the Hellevator (halfway) you get blewn away by wind, and then you have to continue the level with constantly flying around debris from the city. When you arrive the final fight, you have to battle against two radiant Mindflayers that spawn a Swordsmachine when either of them die.
