Megalab

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.

Secrets
(sector 51) plus a rocket launcher, a box of rockets, and a switch. (sector 175) there is a door in the south-west leading to the blue key area. (sector 62)
 * 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. (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).
 * 1) 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),
 * 1) 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)
 * 2) 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 -
 * 1) 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)
 * 2) 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)
