Megawatt

Megawatt (MEGAWATT.WAD) is a single-level PWAD designed by Casey Miller. It was originally released April 3, 1994, and stood out from its contemporaries due to its size and difficulty. A revised version with bug fixes and difficulty settings followed a few weeks later (that file's time stamp is April 18).

Secrets

 * 1) At the start, shoot the middle section of the wall on your right.  It opens, revealing a shotgun. (sector 2)
 * 2) Shoot the back wall of #1.  It opens, revealing a plasma gun.  Both the door and the grey-floored section of the plasma gun room count as secrets. (sector 51)
 * 3) See #2. (sector 52)
 * 4) From the start, turn right and go through the door.  You will reach a room with a staircase - the western section of this room has a secret door on its southern wall leading to a room with a medikit, a chaingun, 4 shotgun shells and a switch.  The switch raises a section of floor in the red key area, allowing the monsters in this area (on medium and hard skills to be killed more easily. (sector 15)
 * 5) After getting the blue key, go through the blue door to the north-east.  It leads across a nukage pit to a lowering platform (there is a baron of hell here on hard skill), behind which is a door.  This door leads to a medikit, 4 shotgun shells, and 3 shotgun guys. (sector 49)
 * 6) Just before the door leading to the final nukage area is a secret door on the east wall which can be opened by shooting.  It leads to a backpack, an |energy cell, and a BFG9000. (sector 151)
