In NM episode runs, get the chaingun also the health and time saved in high-traffic areas will be worth the delay (this seems to be true even for NM100S, where the chaingun is obtained by default on the next level).ДЇor styles requiring 100% kills, a clockwise route around the maze, including the chainsaw area, usually causes leftover monsters to collect near the northwest corner (where they can be gunned down on the way out). NM100S players frequently take two detours to help them survive the maze: getting the green armor in secret #1, and killing one Sergeant in the outdoor area to obtain the shotgun. (A pacifist player can still do this, but he has to use his shoulder.) It is not necessary to kill the Imp guarding the exit switch one bullet or punch sometimes pushes it back far enough for the switch to be pressed. Opening the exit door from the left side seems to prevent the first Imp from immediately walking southward and blocking the small lift. In an episode run, use the shotgun to clear a path through the next-to-last room with a barrel frag at the bottom of the lift. In a straight speedrun, cross the first room along its south edge, which is much less crowded than the north edge.

These are not normally observed, however, because the corresponding sectors (28 and 187) cannot be entered by the player without cheating. Linedefs 134 and 574 have their upper textures on the wrong side, resulting in a Hall of Mirrors effect. Opening this reveals a passage (N) to a ledge overlooking the dark room. In the short piece of corridor between the room with the slime walkway and the elevator to the dark room below, there is a secret door on the left side.This door reveals a secret room (L) with a backpack. On the east side of the maze is another secret door this appears as a computer texture surrounded by two vertical metal beams.This reveals a room (K) with four more armor bonuses. Where the second armor bonus is located, there is a secret door on the east wall. In the passage leading to the chainsaw there are some steps.Shooting the door causes it to open the passageway behind it leads to an outdoor area (J) with a chainsaw on a pillar. On the far west side of the maze there is a secret door behind a green armor (I).In the outdoor area beyond this door (F) there is a soul sphere and a chaingun (and, on UV and NM, a crowd of Sergeants). The switch in secret #1 opens a door in the northern steps which lead up to the tower with the red key.Opening this door reveals a room (E) with a switch, a medikit, a green armor, and a backpack. On the east side of this is a secret door this can be seen from the fact that the texture on the wall is different at this point. There is a construction in the center of the first room (with a passageway through the middle).

Kill the 5 Zombiemen and the Imp, go down the lift, and watch out for that nasty Imp there on hard skill levels, and hit the exit switch Take either one, and go right down the stairs, and open the exit door. Hit the switch and two doors will open (to your left and right). Kill all of them, even the 3 Imps on the high platforms. From the edge of the stairs, get to the other side of the room, and collect the health and ammo, and go down the elevator.Дown here is an 'ambush' of 3 Imps and 3 Zombimen. Kill all 5 Zombiemen and maybe an Imp that comes from a different room on the right, and head straight, going up the stairs killing 2 Zombiemen and 2 Imps. Climb up the stairs in front of you, and when you get to the top, kill the Imp and 3 Zombiemen here, and get the Red Key in this little room. But out here you can get a soul sphere and a chaingun and some chaingun ammo. On skill levels 4 and 5, beware of all the 8 nasty Shotgun Guys here. Go up the stairs, and while you're climbing up, go through the opening to the To the left, and kill the Zombieman in front of you. Grab the goodies in here, andДЇlip the switch (don't forget the backpack), and leave this room. Wall in between the 2 doors until the wall opens. You will be in front of a door,Д«ut go left, and kill the 13 Zombiemen in all corners of this room. Get out of the starting alcove and go right.
