MAP12: Altar Of Pain (Doom 64)

MAP12: Altar Of Pain is the twelfth map of Doom 64 and has the secret exit to MAP30: The Lair. It is designed by Tim Heydelaar and uses the music track "Lamentation Of The Forgotten".

Walkthrough
In order to find the secret exit you need to find a column with a soul sphere on it (the column is shaped like an arrow towards a wall). If you run into that wall you will end up in a cave with a baron of Hell and the secret exit switch. The rest of the level consists of breaching a fort and fighting lots of demons along the until you find the actual altar of pain and the exit.
