E4M4: Unruly Evil (Doom)

E4M4: Unruly Evil is the fourth map of Thy Flesh Consumed in Doom. It was designed by American McGee and uses the music track "Suspense".

Overview
The map title comes from James 3:8: "But the tongue can no man tame; it is an unruly evil, full of deadly poison."

Secrets

 * 1) In the second room, take the elevator up and continue left around the walkway until you reach a green torch. Press it to lower the floor you're standing on. Continue through two archways to get a berserk pack.
 * 2) Return to the green torch and press it again, but only pass through the first archway. The floor in the second room will raise along with the first lift, taking you up to a rocket launcher.

Bugs

 * 1) In the final room of the level, there are Hall of Mirrors effects visible at the top-front of the side compartments when they open, and at the top of the entrances into northern compartments when they are opened and you are inside of them.
 * 2) In the same room, on Hey, Not Too Rough difficulty or lower, the Spectres in each of the northern compartments occupy both the inner and door sectors, preventing the compartments from opening when the switches are flipped unless the player shoots at the doors with the rocket launcher. The rockets will punch through the doors and kill the Spectres with enough blasts. Upon killing them, the doors will open as normal when the switches are flipped.  In addition, the spectres also jam three of the four pillars blocking access to the exit despite not sharing sectors or overlapping. Note that some source ports fix this issue.
 * 3) Also in this room, on Ultra-Violence difficulty or higher, the Cacodemon pairs in the northern compartments are each glued together, and will not move until one of them is killed.
 * 4) Along the south side of the map is a pen containing three Demon that can be killed through the closed pen enterance with any projectile attack (Rocket, Plasma or BFG), though strangely, not hitscan attacks before the wall revealing them lowers. If using a source port with the ability to look up and down, one can also kill them with any projectile attack by firing at the wall behind the back side of the pen. This is because the Demons are actually too big for then pen and their hit boxes expand to outside the pen enterance and also heavilly into the back wall of the pen. Due to specific quirks in Doom's Blockmap code though, the pen will still lower when triggered despite the Demon's hit boxes crossing over the pen entrance and the Demons are able to move once the pen entrance has lowered despite their hit boxes being heavily embedded in the back wall of the pen.
