DO Reborn fully replicates Warhammer: Dark Omen real-time tactics game. Player takes role of Morgan Bernhardt, baddest mercenary army Commander of the Old World.
At the beginning of Campaign player's mercenary army - "the Grudgebringers" consists of just several units. Among them: infantry, crossbowmen, cannon and cavalry. The cavalry unit is led by Morgan himself and if completely destroyed in battle than it is game over. Other units death does not end the game but is highly unlikely since all units are unique and can't be easily replaced with similar units.
