Battlefleet Gothic 2010 Compendium
The 2010 compendium is a full update to the Battlefleet Gothic universe, complete with updated rules, fluff, FAQ and even some new ships. It was written by the High Admiralty; a Games Workshop-sanctioned board of fans who have been charged with all future development of the game. The document and the rules therein are regarded as 'current' (i.e. most up-to-date) by the ruling board of the AdeptiCon tournaments.
