MAP22: Nightfall (called Nightfall -- The Graveyard on the TeamTNT website) is the twenty-second level of Icarus: Alien Vanguard, set in a simulation of a graveyard. It was designed by Gary Gosson. It is notable for containing gravestones bearing the names of every person involved in the development of Icarus.

Map of MAP22

Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Secrets

1. At the beginning of the level, enter the gray stone room from the second and third doors from the west or east. Inside, a health bonus rests in front of a portion of the southern wall with light shining on it. This can be opened to find a box of rockets, combat armor, and a berserk pack. (sector 45)
2. In the library, two bookshelves in the east are situated lower than the others, and have a health bonus in front of them. Open them to find a medikit, a rocket, and a BFG 9000. (sector 251)

Routes and tricks

Although it is intended that you take the staircase to a switch in order to get the red key, the switch can be pressed from behind the wall, allowing immediate access. The trick was first documented by Graham "Grazza" Burgess in his 0:30 UV speed / pacifist demo. (Ic22P030.lmp, within icar_gb1.zip)

Two more tricks, however, allow access to the exit without getting the red key, although it can only be performed on Ultra Violence or higher. The edges of the fountains in the first area have linedef actions that are intended to be triggered in multiplayer only, which seal off the path to the red key and open the exit. However, if you enter the room north of the graveyard, awaken the Arch-Vile, and run toward the western fountain while keeping the Arch-Vile in your sight, you can launch yourself onto the fountain with the Arch-Vile's attack, triggering the linedefs in the process and opening the exit early. The trick cannot be performed on any lower skill level, as the Arch-Vile is not present.

While the above trick would appear to make the map impossible to finish (due to sealing off access to the red key,) a suicide exit can be performed in the exit room by leading the Baron of Hell into the simulation portal, waiting for a bit before entering the portal (so you don't telefrag him,) and letting him kill you with a fireball as you run toward the barrier. If done correctly, your body will slide under the barrier and into the exit teleporter. These two tricks were first documented by Burgess in his 0:26 UV speed / pacifist demo. ([1])
