MAP21: One Flew Over The Caco's Nest (Alien Vendetta)

MAP21: One Flew Over The Caco's Nest (called One Flew Over the Cacos Nest [sic] on the intermission screen) is the twenty-first map of Alien Vendetta. It was designed by Pablo Dictter and uses the music track "Grove" from Hexen. It was one of the few maps to remain unchanged from the first release to the second.

The title of this level is a pun on the title of the novel One Flew Over the Cuckoo's Nest by Ken Kesey (made into a Broadway play in 1963 and a film in 1975), and the name of the Cacodemon.

Strategy
In the first part, if you stand under the descending bars, they will not go down anymore.

 * 1) Near a red inverted cross in the wall near the beginning of the level, there is a flashing wall covered by green vines. Open it to get a plasma rifle.
 * 2) Directly across from the exit teleporter is a skull recessed in the wooden wall. Press the use key on it to open a nearby secret area with a soul sphere.

Non-official
Facing the switch which lowers the bars to the red key room, turn to the north and open the electronic panel at the end of the corridor to get a soul sphere.
