Now that I've gotten your attention, let me explain that this is
not a group dedicated to anything to do with vampires, or roleplaying in the World of Darkness' "Vampire: The Masquerade" roleplaying game.
What this is, however, is a group dedicated to naval wargaming using the "Harpoon" game rules (currently, I'm using the v3.0 rules of the game, published by GDW. I'll be upgrading to v4.1 - published by Clash of Arms games - in the near future).
"Vampires", in naval parlance, refers to inbound SSMs (Surface to Surface Missile) or ASMs (Air to Surface Missile).
On this list, you will find resources that will help educate you on how to play the game, and how real-life technology is transferred into the game itself. Obviously, we will try to avoid overwhelming new players (especially those new to modern naval wargaming) with too many naval or wargaming jargon: they will learn that later, as they learn the system more.
I have played using the Harpoon (the GDW rules) since the late 80s and have found this game to be one of the best modern simulation games out there. I hope that you will find the game as entertaining (and educational - you can't play it and not learn something from it) as I have!
