Megalab is a single-level PWAD designed by Casey Miller, originally released April 30, 1994. It is a largish solo map with an E2-style "castle lab" theme; like the earlier Megawatt by the same author, it features several open areas, completely unmarked secret doors, and packs of cacodemons.

This level appeared on Maximum Doom as MEGALAB2.WAD, E1M8 of NEWDOOM.WAD, MAP10 of #1DWANGO.WAD, MAP02 of DEATHM2.WAD, MAP01 of EP5A2.WAD, MAP01 of FLESHLZ2.WAD, MAP04 of GOODLOR2.WAD, MAP08 of NEWLEV2.WAD, and MAP08 of WADPACK2.WAD.

Other points of interest[edit]


  1. East of the start area is a courtyard with two high doors that are linked by a walkway which is raised by pressing a switch near the blue key. This walkway counts as a secret, however raising the walkway causes it to lose its secret effect, so in order to credit for the secret, it is necessary to step on the walkway sector before pressing the switch. (sector 34)
  2. East of the blue door in the north-west of the level is a room with several barrels. In between the sets of barrels is a secret door (marked with a misaligned texture) leading to a chaingun and a box of bullets (there is also a lost soul on hard skill). (sector 51)
  3. Take the door south-east from #1's courtyard and turn left. Go through the door to a room with a nukage pit and an armor. Approaching the armor without going into the nukage pit lowers a wall, revealing a room with a demon (on easy and medium skills) or a cacodemon (on hard skill), plus a rocket launcher, a box of rockets, and a switch. As the linedef that lowers the wall (linedef 1025) has Action 37, which changes the texture of the lowered wall (sector 174), the wall will assume the Secret effect of its neighbouring sector, thus enabling 114% secrets to be obtained. (sector 175)
  4. West of the start area is a staircase that curves round to the west. Halfway up this staircase is a secret door on the outside leading to a rocket and a stimpack. (sector 258)
  5. Pressing the switch in #3 raises a bridge from the room reached via #4 to a BFG9000. If you fall into the water here you are not trapped - there is a door in the south-west leading to the blue key area. (sector 62)
  6. Go north from the start area and take the right fork. Through the door is a room with a staircase. There is a secret door on the north-east corner of the staircase, which leads to a passage with several zombiemen. (sector 210)
  7. Approaching the blue key opens up two traps. The eastern one has a secret door on its back wall leading to a chainsaw and a door back into the exit room. (sector 249)
