UACPEN

UACPEN is a single-level PWAD for Doom that was designed by The Mad Hacker in August 1994.

Secrets

 * 1) The room with the crates containing the switch which opens up the corridor to the blue key room has a secret door to the north (marked with a misaligned texture) leading to two shotgun guys (one on easy skill), a rocket launcher, a box of rockets, and (on multiplayer) a box of shotgun shells. (sector 404)
 * 2) The blue key room has a secret door in the north-west leading to a soul sphere. (sector 242)
 * 3) In the east is a large room with a rocket launcher and some boxes of rockets. This room has a secret door on the west wall leading to a partial invisibility. (sector 462)
 * 4) North-east of the central room is a room with three switches on a panel. Part of the ledge here has a different texture - it lowers on pressing, allowing access to an area with 1-3 imps, two medikits (one on easy skill), a backpack, and some ammo. (sector 129)
 * 5) There is a secret lift in the north-east of #3 leading to an area with a soul sphere.  At the south of this area is a lift which lowers on pressing the western wall, allowing access to an area with two imps (one on easy skill) and a chainsaw (there is also some ammo on multiplayer). (sector 128)
 * 6) The closet six to the east of the yellow key closet has a switch which lowers the floor, allowing access to a maze. Directly opposite this lift (to the north) is a secret door leading to two medikits (one on easy skill), a third medikit (multiplayer only, not on easy skill), a box of rockets, an energy cell pack (two on multiplayer, three on hard skill multiplayer). On easy skill there is also a plasma rifle - on other skills the plasma rifle can be obtained by opening a secret door to the west (where there is instead an energy cell pack on easy skill). (sector 334)
 * 7) After going through the yellow door to the west, head through two more doors then turn south and through one more door. Carry on ahead - a door will open ahead revealing a monster closet. This closet has a secret door to the south leading to a soul sphere and a box of bullets. (sector 391)
 * 8) After the floor of the central area is lowered, there is a secret door to the north-east (marked with a green texture) that can be opened, revealing an invulnerability. (sector 431)
 * 9) Just before the exit is a secret lift to the north, leading to a baron of Hell (two on multiplayer) and two medikits. (sector 176)
