Pirates of the Vistula is an adventure module for Twilight: 2000. The mighty Vistula River sets the stage for a journey from Krakow to the remains of Warsaw aboard the river tug Wisla Krolowa. But the Vistula has seen better days. The river has been left untended for years as the war raged around it, and now is overcome with debris and sandbars. In addition, Pirates of the Vistula provides complete rules for a new type of warfare in the world of Twilight: 2000 — riverine combat. Image:Stub.png. You can help My English Wiki by expanding it.
