E4M2: Perfect Hatred (Doom)

E4M2: Perfect Hatred is the second map of Thy Flesh Consumed in Doom. It was designed by John Romero and uses the music track "Donna to the Rescue." In the Doom Classic port, it has a par time of 4:15. It features a secret exit to E4M9: Fear.

Its open yet compact design means that the player will immediately alert and face a mass of monsters at the start, particularly a concentration of imps and cacodemons, without much cover and in very close quarters. Also, as much of the level consists of platforms above damaging lava, some skill is needed in making the "jumps", often while dodging enemy attacks.

The Sony PlayStation and Sega Saturn versions of Doom lack the exit to the secret level, Fear, as they do not include that map.

Overview
The map title comes from Psalm 139:22: "I hate them with perfect hatred; I account them mine enemies."

Essentials
If starting ammo and health are not enough, you can fall into the slime and look for the supercharger and pick up the shell ammo in the tunnel back to the start. Mind the cacodemon waiting down in the slime right in front of the starting area.

The circular lava room in the southwest corner of the map has a platform which contains a plasma rifle - but when the player tries to grab it, barons of Hell emerge from hidden walls directly ahead of and behind the player. The eastern edge of the southern trap has a hidden switch which raises some of the wooden structure in the centre of the level, giving the player more room to move around.

The teleporter from the barons' room in the west has a secret next to it that leads to the other side of the teleporter, which leads to the north-west niche containing a megaarmor and other items. From there, you can normally jump back on the platforms in the center, or if you coordinate your jump properly, you can reach the stairs beyond the blue column.

From the same megaarmor niche, you can use the grab trick: run as fast as you can (helped by strafing at the same time) in the direction of the cyberdemon niche. If you go in the correct direction and coordinate the run properly, you'll be able to grab the BFG behind the wall, early.

The cyberdemon can be defeated by telefragging. As soon as you reach the sky-lit top area, a teleporter on the central platforms opens, which will bring you right on top of the monster, killing it. From there, you will be able to access the secret level, E4M9.

Secrets

 * 1) In the smaller, isolated lava pit in the southwest of the level, drop into the lava and flip the switch to raise a bridge. Step into the small triangle of lava next to the switch to open an exit out of this pit. At the top of the stairs is a teleporter. Open the wall to the left just before the teleporter; behind it is a secret cache. (sector 70) The right wall at the back of the secret room also opens, and you can take the other side of the teleporter to a separate secret room with a blue armor and a box of rockets.
 * 2) After opening the blue "door", run up the stairs and across the raised platform with the cyberdemon guarding it until you hear the sound of a door opening behind you. Run back down to the lower wooden platforms, and a teleporter will have appeared. Go through it to telefrag the cyberdemon, saving you a lot of work. (sector 74) Pick up the BFG and lower the wall in front of you to exit.
 * 3) Secret exit: Upon lowering the wall to exit secret #2, a wall back down in the western wall of the main lava pit will lower temporarily. Quickly run into the opening to reach the exit to E4M9: Fear. (sector 17)

Bugs
There are 3 known anomalies in this level's REJECT table.

Design oddities
It is possible to pick up the BFG9000 quite early in the map by bumping it from inside the small room next to it. From this area you can jump down to the stairs on the other side of the blue skull bars, negating the need for a blue key.

Routes and tricks
It is possible to bypass any use of the keys by straferunning to the right of the blue pillar from the room with the megaarmor. This trick was first made by Steffen Winterfeldt, and therefore now commonly said as "Steffen Winterfeldt Jump". However, for most people, it may take at least two tries.
