KZDoom6

KZDoom6, titled Hidden Valley of the Aliens, is a single-level PWAD for Doom II and the ZDoom source port that came out in December 2000. It was designed by Kurt Kesler as the sixth entry in his KZDoom mini-series. It uses the music track "DOOM" by Robert Prince and made it into the Top 100 WADs of All Time as an entry for the year 2000.

Secrets

 * 1) In the blue key building, a megasphere is hidden near the steps leading to the blue key room (not the steps leading to the key itself). Just go through the wall at the end to find it. (sector 230)
 * 2) When you first head outside, hug the southern valley wall all the way until you reach a dropoff point. If you drop into the cave near the building, you will find a soul sphere, a plasma gun, and an energy cell pack. (sector 311)
