W.G. Armintrout

GURPS 3e set adventure. Players to pick a trope and build. It needs players willing to go along for the ride but a good short adventure scenario. Possibly the seed for a longer campaign in a Mulder and Scully style. Recomended but would need to be ammended if usiong 4e.

Steve Jackson Games says "The Horseclans solo adventure Up Harzburk! was recalled soon after publication, in early 1989, because it contained so many path errors that we did not feel it could be adequately corrected by an errata sheet." Need I say more? It's got some random tables and maps, but it's really only of interest to a collector.
