or two hundred years, the Imperium of Mankind has laid siege to the galaxy, its all-conquering armies spreading outwards from Terra to unite all humanity under the Emperor's banner. Now, as the galaxy burns in a brutal civil war, the Horus Heresy takes to the skies in the ultimate test of aerial supremacy.

This Aeronautica Imperialis rulebook provides complete rules for bringing the dogfights and airborne sorties of the Horus Heresy to life on the table, as players pit Loyalist and Traitor aircraft against each other in deadly aerial warfare. It's everything a newcomer to Aeronautica Imperialis will need to learn how to play games set in the Age of Darkness, and a great reference book for veteran players.

- A complete set of core rules for playing games of Aeronautica Imperialis, from shooting down enemy aircraft to giving your pilots ace skills
