The Tormented Fortress is a CTF conversion of Chambers of Torment - one of id Software's original Quake levels - by John Schultz for the CTF Expansion Project and 32 player QuakeWorld Deathmatch. E3M6 is the final (non-secret) level in Quake's third episode, and this version uses its Rune Bridge/Episode Portal section as the joining point between the two flag fortresses.

The conversion is masterfully done, but there's little changed here from American McGee and Tim Willits' original design except in texturing, so please refer to the original review for more information.
