MAP01: Entryway is the first map of Doom II. It was designed by Sandy Petersen and uses the music track "Running From Evil".

In the PlayStation and Sega Saturn joint port of Doom and Doom II, Entryway is MAP31, and is the port's first Doom II level.

Walkthrough

 * Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Essentials
Jump down from the ledge. Enter the corridor in front of you, head east at the first bend, and go south at the next. Enter the door at the northeast of the next room, and flip the switch.

Other points of interest

 * 1) At the very start of the map, before climbing down to the floor, head southwest to access a partially open-air area and get a chainsaw.
 * 2) At the northeast of the winding corridor, there is a room containing eight health bonuses.

Secrets

 * 1) In the blue room at the north of the level, flip the easternmost switch. A compartment will open in the northeast of the room, containing a suit of armor and two stimpacks. (sector 41) Toggling the opposite switch will cause both switches to sink into the ground, allowing the zombiemen's clips to be acquired.  If you do this, you can still open this secret by pressing the Use key where its switch was formerly located.
 * 2) In the large room at the end, toggle the switch to the west to activate an elevator.  At the top, open the back wall of the elevator to reveal another switch. (sector 8) Flip it to open a door in the southeast leading outside.
 * 3) From secret #2, jump east across the square platform below.  A compartment containing a rocket launcher will open behind the health bonuses out in the hallway. (sector 57) You do not have to jump onto the platform; all that is required is that you jump over the platform's west side (linedef 242.)
 * 4) After activating the switch in secret #2, head outside through the door opened in the southeast.  To the west is a shotgun and 4 shotgun shells. (sector 17)
 * 5) In the big room, one side of the wall to the east is perfectly straight.  On the north end of this wall is a cage containing an imp.  Open the other end of this wall to find a stimpack. (sector 28) On Hurt Me Plenty or higher, two imps will exit this secret if you fire your weapon inside the room or at the end of the corridor that leads into it.
