BFG has had, over the years, a few lists published in 'official' materials that were never made 'official'. Due to all the talk about the Bakka list again, I figured I'd break out a few of the old apocryphal lists, starting with the Corribra list from Planet Killer (granted with clarifications/changes from the old Corribra website).
Battleships:
Emperor
Retribution
0-1 Nemesis
Battlecruisers
Mars
Jovian
Overlord
Cruisers:
Tyrant
Gothic
Dictator
Lunar
Dominator
Dauntless
Siluria
Escorts:
Firestorm
Sword
Cobra
For those not familiar with the Nemesis fleet carrier, it's a battleship with 12 lbs.
