I have seen mention of a Battlefleet Gothic module, but cannot find it–is it still available?
You can download the newest version from the V Battlefleet Gothic yahoo group.
Or directly here: VBFG on mediafire.com.
Is someone actually using it? never seen anyone online
There is also Alternate Battlefleet Gothic for Vassal. It uses hex map and I prefer it.
