Defragmentation Factor is a single-level PWAD for Doom II that was released on December 9, 2006 by Eugene Guschin (Wraith777). Built using a combination of Doom and Doom II textures, this sprawling map has many themes including techbase, caverns, marble temples and outdoors areas.

Custom monsters[edit]

The WAD includes two new enemies through the DEHACKED lump:

Plasma Gunner
A red-colored zombie marine which fires four arachnotron plasma balls in rapid succession. It has 150 hit points and replaces the gibbed marine.
Double Gunner
A brown-colored zombie marine which fires two shotgun blasts identical to the shotgunner in rapid succession. It has 200 hit points and replaces the dead lost soul.

Other points of interest[edit]


  1. Head up the steps west of the starting room and to the south door. Take the east door and look north. Shoot the lion switch to the north to open the south wall, which is a passage leading to ammo and a medikit. (sector 175)
  2. At the end of Secret #1, open the wall and head southeast to a cave, heading all the way to the partial invisibility at the end. (sector 645)
  3. In the east room with the faces in the caged columns, open the dark gray monitors to find a green armor. (sector 730)
  4. In the east room with the soul sphere, open the north door and head east up the steps to a switch. Flip the switch on the back of this switch, then head back to the door and go north past the bars that are now open to get a box of shotgun shells, energy cells, and a berserk pack. (sector 666)
  5. Head back to the hall that had the entrance to Secret #1, then head to the west door and into the room with crates. Doing this opens a wall in the previous hallway. Head back and up the steps, then to that new area. Open the north wall, then use the switch at the east end to lower the blood. Head northwest and use the west wall to enter a secret room with stimpacks, shotgun shells, a medikit, a chainsaw (flip the switch), and energy cells. (sector 793)
  6. At the end of Secret #1, open the wall and enter the cave. Use the gray wall at the northwest end and ride it up. Open the west wall to reach the south maze. Go to the northwest part of the maze and at the health bonus, open the north wall to get to the high crates in the room with crates. (sector 220)
  7. In the same maze, head to the south end, then west, just before a box of shotgun shells. Open the south wall to get ammo clips, stimpacks, and armor bonuses. Stepping into the southwest light will lower the computer area map to the east. (sector 368)
  8. In the blue key room, go under the light with the armor bonus below it and the north door will open. Go up the steps behind it and head to the teleporter to the east. (sector 340)
  9. In the area you teleport to from Secret #8, unlock the southwest bars, then jump to the area behind them. To the south is a pillar with an energy cell pack. Press on the unlit gargoyle switch to lower the energy cell pack. (sector 395)
