Rich Text FormatThe following are Shadowrun net.sourcebooks and similar publications that were never (and still aren't) Plastic Warriors publications, but which have been put up here to make sure they're available somewhere for the collectors and others who care about the game's ancient history.
Note that some of these documents may have various issues that will prevent them from looking quite the way they were intended by their creators. Missing fonts can be a big issue, as are — with Word documents — things shifting to other pages than they're supposed to be on.
Furthermore, in an effort to make the files more usable in the modern day, when PDF is pretty much universally supported, the Plastic Warriors crew has braved considerable dangers to life and happiness by converting most of the ones that weren't originally released as PDF files, to that format as well. This wasn't as easy as it may sound for a lot of the files, given that the objective was to make them appear as thye should, including formatting, the right fonts, etc. — none of it was a simple “Print to PDF” job.
Thanks also to Lars Wagner Hansen and Peter Steen Kristiansen for sending additional net.books for inclusion. Also thanks to Lars again and to Rob “NightLife” H. for supplying some PDFs of files not originally available in that format, even if those don't actually appear below … :)

This is a catalog of 20th-century military aircraft and a few boats, and some additional game rules and weapons for them. (It is, in fact, a Shadowrun conversion of the Nautical/Aviation Handbook for the second edition of Twilight: 2000, covering exactly the same boats and aircraft that does, but with entirely new text. There was also a hardcopy version that the author provided to some of his friends, which had illustrations taken directly from that book, but the version here is a text-only Microsoft Word document.)
