Sapidus

Sapidus is a single-level PWAD for Doom. It was released in 1994 by Eddie Nguyen, and is the fourth in a series of single-level wads, following UCA, Talpoida, and Diopatra. Unlike the other levels, it had two releases: SAPIDUS.WAD on June 5, 1994; and SAPIDUSB.WAD on June 9, 1994, the only version available on the idgames archive. The second release fixes an error with the slime pits in the level (see Bugs).

Secrets

 * 1) Immediately to the south of the north-western room, the eastern door has a secret door leading to a room with a box of bullets and a medikit. (sector 31)
 * 2) Immediately north of the medikit in #1 is another secret door leading to a room with three spectres and a medikit.  There is a secret lift in the south-west of this room, which on pressing reveals two switches.  The eastern one raises a bridge ahead, on the other side of which is a door leading to a room with a spectre and two lost souls. There is another secret door in the south-west of this room. (sector 180)
 * 3) Go west from the north-eastern room.  The northern wall has a secret door leading to a backpack. (sector 79)

Bugs
In the original release, SAPIDUS.WAD, the slime pits in each corner of the level (sector 15) use sector effect 11, a 20% damaging floor that hurts you through the radiation suit, but also ends the level when your health drops below 11%, enabling an unintentionally quick exit. The second release, SAPIDUSB.WAD, changes this to sector effect 16, a 20% damage floor with a small chance of hurting you through a radiation suit, to fix the error.
