"For narrative players, you’ll be able to get stuck in with an in-depth set of rules for fighting in the cities and ruins of the Mortal Realms in Streets of Death. New mercenary companies allow you to add a selection of narrative-led, thematic units to your army. Perhaps you’ll employ the Maneaters of the Gutstuffers, or a Gargant from the notorious Grugg Brothers. Meanwhile, characterful name generators for loads of factions mean you’ll never be with our an appropriately epic moniker for your favourite Hero!"
