It is only legal to play Horus Heresy games with Horus Heresy miniatures which you have bought for full price from Forgeworld or GW web store or physical shop. Please remember that this legality also extends to paints, glues, brushes and basing materials. Please ensure that all your hobby supplies are official GW products. Failure to comply with this will result in you being arrested by the Game Workshop Police, detailed at the Emperors pleasure and perma-banned from the hobby.
