MAP22: Vertigo (Herian)

MAP22: Vertigo is the twenty-second map of Herian. It was designed by Ian Wilson.

Secrets

 * 1) Head to the large set of steps, then north of them, on the ground. Head east and when you see a valley to the south where you can get a megasphere, go through the north wall to get an invulnerability. (sector 155)
 * 2) Get the blue key and head back. Use the switch and go to the lowering wall. Open the door there to get an energy cell, an energy cell pack, and a plasma gun. (sector 174)

Bugs
Two pools of blood and flesh (Things 133 and 134) have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
