MAP01: Water Facility is the first map of Congestion 1024. It was designed by Nick Laurent (hobomaster22). It uses the music track "Backroad Wanderer," composed by David Shaw, which originally appeared in Memento Mori IIMAP10.
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[]
On the west side of the southwest tower is a small switch. Throw the switch to open a door near the start of the level containing megaarmor. (sector 91)
The waterfall directly to the east of the bridge can be walked through, leading to a box of shells, a shotgun, a stimpack, and a teleporter leading back to the start of the level. (sector 18)
Bugs[]
It is possible to grab the megaarmor in secret #1 through the door before you open it by running into the door. No straferunning is required to pull this off, although it is best to start from the opposite wall.
