Engines of Babylon

From the back of the book:

The Cold Stars Await Your Tread

Engines of Babylon gives you all the tools you need to add custom vehicles and low-tech system ships to your Stars Without Number campaign. From gravitic yard skiffs to main battle tanks, this all-new, previously unpublished SWN supplement, available in this bundle and nowhere else, lets you build system ships for campaigns set in the near future.

In Engines of Babylon you'll find a mighty trove of priceless treasures to reward the curiosity of reckless freebooters -- whether as trophies of a fabulous adventure, or as savage harbingers of a hostile power. A selection of maltech horrors should whet the appetite of any remorseless villain worthy of the name.
