  1. At the northeast corner of the map, take the southwest steps up and enter the passage leading to two arch-viles, a soul sphere, and a switch. Open the vent to the right of the switch to find a medikit and three energy cell packs. (sector 3767)


Two boxes of shotgun shells (Things 4100 and 4101) have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
