Editing E1M9: Military Base (Doom)

{{Knee-Deep in the Dead|consolever=MAP24: Military Base (Console Doom)|snesver=E1M9: Military Base (Super NES Doom)}}
{{map|slot=E1M9}}
'''E1M9: Military Base''' is the [[secret map]] of [[Knee-Deep in the Dead]] in [[Doom]], which can be accessed from [[E1M3: Toxin Refinery]]. It was designed by [[John Romero]] and uses the [[Doom music|music]] track "Hiding the Secrets". The [[par time]] is 2:45.

Completing this level takes the player to [[E1M4: Command Control]].

===Essentials===
You begin in a short corridor; at the end of this corridor is a large courtyard (''A'') containing [[imp]]s in a cage.  Go down the stairs to the west and get the [[yellow key]] behind the fence (''B'').  Return to the courtyard and go down the stairs to the east.  Turn right, open the yellow door, and pick up the [[red key]] (''C'').  Leave the room through the other yellow door, continue west through a room with a large "box" pillar surrounded by four [[Thing types#Obstacles|torches]], and go down the stairs and through the red door.  Cross to the far wall of that room and turn left; you should see a switch behind a row of [[barrel]]s (''D'').  Shoot the barrels from a safe distance and press the switch.  This raises the "box" pillar in the previous room to reveal the [[blue key]] (''E'').  Get the blue key, then return to the central courtyard and go down the stairs to the north.  Behind the blue door is the exit room; the exit switch is visible across a [[Damaging floor|nukage]] canal, but inaccessible (''F'').  Jump into the canal and follow it around (in either direction) to a platform (''G'') with a green switch and an imp.  When you step onto the platform, a passage will open behind you (''H'').  Click the switch, then enter the passage.  Follow it to a lift (''I''), and go through the hidden door at the top of the lift.  You will now see a wide bridge across the canal.  Cross the bridge and activate the exit switch.

===Other points of interest===
If you are starting this level from scratch, the [[sergeant]]s in the central courtyard (four on [[Hurt me plenty]], eight on [[Ultra-Violence]] and [[Nightmare!]]) may cause you a lot of trouble.  Stay as far away from the courtyard as possible until you kill a sergeant very close to the short corridor, then grab his [[shotgun]].  Alternatively, as soon as you have killed the [[zombie]]s emerging from the south staircase, run down that staircase and get the [[chaingun]] (see secret #1 below).

To the north of the yellow key room is a room containing a [[rocket launcher]] (''J'').  When you step onto the red star, however, a pack of [[monster]]s will begin [[teleport]]ing into the room. On HMP and higher the player must fight a large number of demons with no reward (ammo or health) afterward, so the weapon acquisition must be weighed against the drain on the player's other resources.

In the room east of the central courtyard, the brightly lit area along the east wall is really a lift (''K'').  This brings you to an outdoor area containing three tall pillars with imps on top, as well as a [[medikit]] and a [[green armor]].  Crossing to the [[Item|powerup]]s will cause the pillars to lower.

Taking the red key opens a trap in the southeast wall of the room (''L''), revealing additional monsters and [[Item#Health|health pickups]].  With great care, it is possible to pick up the key without triggering the trap.

The switch that reveals the blue key also opens a second passage (''M'') back to the previous room (on the south wall, behind some other barrels).  It contains a medikit, a [[Box of bullets|bullet box]], and a [[Box of shells|shell box]].  The blue key is guarded by two demons ([[I'm too young to die]] and [[Hey, not too rough]]), or six demons (HMP), or eight demons (UV and NM).

When you step onto the platform in the nukage canal, an imp (ITYTD and HNTR), or three imps (HMP), or four imps (UV and NM), will be released as the new passage opens.  At the same time, a trap opens next to the exit switch (''N''), releasing a [[spectre]] (ITYTD and HNTR) or three spectres (HMP, UV, and NM); watch out for these as you re-enter the exit room, since they may cross the bridge immediately.

===Secrets===
# In the room east of the central courtyard, a hidden lift in the southwest corner (''O'') drops down into a nukage pool. In the room south of the central courtyard, a hidden lift in the northeast corner (''P'') drops down into the same nukage pool. You can get a chaingun and a large number of [[Box of bullets|bullets]] there. ('''sector 65''')
# In the exit room, there is a secret door in the center of the east wall, indicated by a different [[texture]]. Behind this door ('''sector 20''') is a room with items atop pillars (''Q''), including a [[backpack]], a [[chainsaw]], and several large [[ammo]] pickups. As you reach the bottom of the staircase, a lift will drop near the far wall, allowing you to ride to the top of the tallest pillar. To collect the items, jump carefully from pillar to pillar: back up as far as you can without falling off, run toward the next pillar, then stop quickly as you land. If you make a mistake, just return to the steps to lower the lift again. It is easiest to go around the pillars counterclockwise, from highest to lowest.

===Bugs===
Entering the southern area of the yellow key room may awaken an imp (Thing 52) in the room to the south, even though there is a locked door between you. This is an instance of the [[Sleeping Sergeant of Doom II MAP02|"sleepwalking sergeant" bug]]: the imp is at (-576,-960) and one of the linedefs on the staircase is at y&nbsp;=&nbsp;-576.

The [[Flawed collision detection|blockmap bug]] sometimes occurs in the short corridor where the player starts.

There are 7 known [[Blind spots in Doom reject tables#E1M9: Military Base|anomalies]] in this level's [[REJECT|REJECT table]].

===Design oddities===
The ceiling of the platform in the nukage canal is high enough that the switch texture tiles twice vertically. It is possible to see the bottom part of the second switch when approaching the platform from the north.

== Speedrunning ==

===Routes and tricks===
The shortest route through this map is to enter and leave the [[red key]] room through the west door.  Some luck is required to survive a straight speedrun: the group of [[sergeant]]s in the red key room often inflicts a large amount of [[damage]], and the [[demon]]s guarding the [[blue key]] can easily surround you (especially if you kill only one or two with [[Barrel|barrel frags]]).

The switch that reveals the blue key can be pressed without destroying the barrels.

It is possible to jump over the [[Damaging floor|nukage]] canal in the exit room by [[straferun]]ning. This trick was invented by [[Uwe Girlich]].{{cite web|author=[[Uwe Girlich]]|title=E1M9-042.TXT|url={{competnftp|doom/max/e1m9-042.zip}}|publication=COMPET-N|publishdate=1995-08-14|accessdate=2006-02-24}}

When playing on NM, most players make a detour either to the [[chaingun]] or the [[rocket launcher]], in order to clear paths through crowds more quickly.  The second method is more dangerous, since it releases fifteen extra [[monster]]s, but faster, since the rocket launcher is so powerful.{{cite web|author=[[Jonathan Rimmer]]|title=n1m9-050|url={{competnftp|doom/nmare/n1m9-050.zip}}|publication=COMPET-N|publishdate=2000-08-06|accessdate=2006-02-24}}

For styles requiring [[Intermission screen|100% kills]], the most efficient approach is to ignore the monsters in the central courtyard, then run in and out of the rocket launcher room after getting the [[yellow key]].  By the time you clear the red key room, most of these monsters will have collected at the foot of the staircase to your west.  (Because of the open layout of the level, however, this may backfire as monsters wander up to the central courtyard and enter other rooms.)  [[Anders Johnsen]] credits [[Yonatan Donner]] with inventing this route.{{cite web|author=[[Peo Sjöblom]]|title=E1M9-248|url={{competnftp|doom/max/e1m9-248.zip}}|publication=COMPET-N|publishdate=1997-06-27|accessdate=2006-02-24}}{{cite web|author=[[Anders Johnsen]]|title=T1M9-531|url={{competnftp|doom/tyson/t1m9-531.zip}}|publication=COMPET-N|publishdate=1999-03-07|accessdate=2006-02-24}}

A small amount of time can sometimes be saved in the exit room by not killing anyone until the bridge is raised.  With luck, the spectres will gather near you as you emerge from the lift, and some will be damaged by the [[imp]]s and sergeants (and therefore not attack you right away).

In [[NM100S]], the fastest way to reach [[secret]] #2 is to jump across the nukage canal, shoot the deaf [[spectre]]s with [[rocket]]s, then jump back across the canal to the secret door.  If you are out of rockets, you can instead run through the secret door immediately, so that only one spectre approaches you at a time.  For an episode run, the extra rockets in secret #2 and the extra bullets in secret #1 are both good investments.{{cite web|author=[[Vincent Catalaá (Peroxyd)]]|title=E1ns1506|url={{competnftp|doom/movie/e1ns1506.zip}}|publication=COMPET-N|publishdate=2000-08-31|accessdate=2007-02-27}}

A small amount of time can be saved in [[UV -fast]] mode by approaching the blue key through the south passage, then firing into the room ''between'' the barrels.  [[Zombie]]s will often enter from the central courtyard and start [[Monster infighting|infighting]] with the demons.  (This is dangerous, since a stray pellet may cause the barrels to explode.)  In episode runs, secret #2 is sometimes entered fully in order to restock on rockets.

Due to the number of demons and spectres on this level, [[UV Tyson]] runs are fastest when the [[chainsaw]] is obtained quickly (clearing only the red key room and the room with the blue key switch).  The [[green armor]] is important for surviving all the way to secret #2.
