Dubbed by its authors as the Lost Generation this 5th edition of In Nomine Satanis / Magna Veritas (INS/MV) is supposed to the ultimate one.
In a modern day alternative world, angels and daemon have been fighting each other, being pawn in a gigantic battle chess between God and Satan that started on the day Jesus Christ was born. Players play angels or daemon depending on the side chosen, and they answer to they superior in the hierarchy, from heaven or hell. This with a lot of humour and satire,
In the 5th edition things change: in 2006 both heaven and hell gates have been closed, and the Angels and Daemon are left on Earth without any way to communicate to they chiefs. This end up in a guerilla style conflicts where the bigger picture of the battle is left aside.
The 5th edition feature a new rule system still using the 666 dice (3 d6) that is designed to be very simple.
