Have there been any official rules posted for void hardened armour? It features in a certain grimdark tabletop wargame, but I don't know if it's been ported to Dark Heresy yet. If so, please point me in the right direction. And no, I don't have all the rules supplements. Yet.
(Short version, it's an armour modification. Slows you down a bit, but improved protection against blast / spray and better resistance to void conditions.)
Cheers,
