From publisher blurb:
This second issue of 0-hr Sci-Fi Settings presents a headquarters in two parts - corresponding the two sides of the HQ-1 poster. The first part is House Overlund: an urban estate that combines a classic mansion with high tech facilities designed with off-duty adventurers in mind. Far beneath the mansion lies the second part of this offering: the underground base. This section of the headquarters holds barracks, science labs, a detention center, and other elements that are better hidden from prying eyes.
This product contains:
Two 24x36 inch jpeg images at 150 dpi. The front and back of the poster (versions without text labels also included).
An eighteen-page PDF file with room by room descriptions and additional information about the locations.
Two PDF documents of the poster broken into pages for easier printing. Each is 3x4 pages.
There are elevators and a large vehicle lift that connect the above and below ground sections of the HQ, but it is also possible to use the sections on their own. House Overlund is still an impressive estate with ample room for a group of ambitious heroes. But it could instead be the home of a wealthy industrialist or a location that must be covertly explored.
Likewise, the underground base can be situated beneath or within any area that could feasibly accommodate an elevator shaft and the retractable landing pad. It could be under any sort of building, out in the wilderness, or even buried within ice or an asteroid. Both sections have enough room and support facilities to make sense on their own - so make use of them however you like
