E1M1: Hangar (Doom)

E1M1: Hangar is the first map of Knee-Deep in the Dead in Doom. It was designed by John Romero and uses the music track "At Doom's Gate". Being the first map in the game, it is small and straightforward, with a par time of 30 seconds.

Strategy


There are no keys in this map. Non-secret items include one green armor. Secret items include one shotgun and one blue armor. On Ultra-Violence and Nightmare!, the shotgun can also be obtained by killing sergeants. For more detailed monster and item data, refer to the statistics section below.

Walkthrough
To the left of the start room is a platform with a green armor on a pedestal. If you play on Ultra-Violence or Nightmare!, watch out for the sergeants that guard it; there are two by the armor and one behind each of the columns by the staircase. They can cause quite a bit of damage due to their awkward positions, but on the positive side killing them gives you an early shotgun.

Return to the start room and go to the corner on the opposite end of where you started. Continue through the door to enter the central computer room. On the lower skill levels you'll now face the first enemies in the game, two zombie guys (one on I'm Too Young To Die and Hey, Not Too Rough). On UV and NM, there are additionally four sergeants in the room to deal with.

Proceed and you'll enter a large room with a nukage pool across which goes a zig-zag bridge. Take down the possessed humans and the imp (two on UV and NM) on the platform. Optionally collect secret #1 before entering through the next door.

In the last room before the exit, detonate the exploding barrel to take out the enemies in front of you (one imp on ITYTD/HNTR, an additional sergeant on UV/NM), and on UV/NM detonate the barrels behind both fences to clear out the four zombie guys on the sides. Before you enter the room with the EXIT sign and press the switch to continue to E1M2: Nuclear Plant, optionally go back to collect secrets #2 and #3.

Secrets
There are 2 secrets in this map in version 1.0:


 * 1) In the corridor at the end of the zig-zag room (sector 52), the wall on the right (linedef 243) is miscolored and has a corpse lying next to it. Activate the wall to get access to the courtyard (sector 1) with the blue armor. In the Ultimate Doom version of the map, the blue armor can also be reached by activating the switch on the side of one of the tech columns (linedef 136) near the green armor, which opens a door (sector 4) next to the window where the player started.
 * 2) After having entered the dark room with the exit door (sectors 64, 65), return to the zig-zag room (sector 56). The platform with the imps (sector 55) has now been lowered, yielding access to a secret room (sector 54) containing a shotgun.

The following additional secret was added in version 1.2:


 * 1) After opening #2, go near the entrance of the zig-zag room (sector 15). As you cross the shadow line (Linedef 191), a lift will lower (sector 87) in the shotgun alcove (sector 54), visible from where you are standing. Run and you'll catch it before it goes up. It also contains a fake see-through wall, first occurrence in doom.

The following additional secret was added in version 1.9:


 * 1) Next to the start in the alcove with green armor there are two pillars. The north pillar has a switch which opens up a door to the outdoor area with the rocket launcher.  After a player walks through this secret door, another door will open up making the map much more open. It is now possible to go to the outdoor area from the central computer room. This secret was likely added to improve gameplay in deathmatch mode since it adds two extra ways to reach the rocket launcher.

Routes and tricks
For a straight speedrun, the simplest path through the map is also the fastest one, and there are no tricks. However, the route through the outdoor area is often used in episode runs since this gives a blue armor (which helps surviving E1M3: Toxin Refinery) and a shotgun.
