MAPB: The Invisible Man is the second map of Keeper of the Seven Keys 3 (Disc One). It was designed by David Newton (DavidN) and uses a MIDI rendition of "The Invisible Man" by Helloween as its music track. This map is heavily based around the invisidemon custom monster, with the first half of the map featuring almost exclusively rocket launcher-centric gameplay that is made more challenging due to these invisible enemies.

1. In the yellow key area, head to the cage at the east end, then look up to the east and shoot the switch to open it. You can get ammo and a soul sphere here. (sector 132)
2. At the north hall, just before six health bonuses, lower the west wall to get two grenades. (sector 464)
3. In the northernmost room, press on the dimmest wall to the east to find a berserk pack, health bonuses, armor bonuses, and a box of rockets. (sector 508)
4. Cross the bridge in the center of the map going south and lower the wall directly south of you to get a heavy armor. (sector 589)
