This is the lore mod I have been working on with PistonMiner, Caliger and Ahzek Ahriman for Battlefleet Gothic Armada. It aims to add more ships, more weapons and bigger battles.
PistonMiner has fixed the Nova cannon and the Imperial UI bugs, so here is PR 1 hotfix. Replace your BattleFleetGothic-PistonMiner.pak in the Steam\SteamApps\common\Battlefleet Gothic Armada\BattleFleetGothic\Content\Paks folder.
