Map scrolls in Heretic reveal all areas in map mode, unless the affected areas are indicated to be completely invisible in map mode by the map authors. Unexplored areas are indicated in gray lines. This functions just like Doom's Computer map. Normally available in standard Heretic maps near the end of the map's gameplay, it is useful for locating secret areas missed otherwise.
