Welcome to Imperius Dominatus

Imperius Dominatus is a 6mm-scale large-scale tabletop miniatures game set in the Horus Heresy.

Imperius Dominatus uses 10-sided dice (D10s) to permit truly large battles in 6mm “epic” scale. It draws its inspiration from the many previous “epic”-scale rulesets (such as NetEpic), as well as many original ideas and mechanics. Scenarios permit games to be played in an afternoon with a built-in turn limit, or just play freeform for as much time the players have.

The ruleset and army lists capture the breadth and scope of units and formations from the Horus Heresy, as they currently exist in the larger miniature scale. As it grows and adds new units and formations, so will Imperius Dominatus.

Have fun and enjoy the game!
