Diplomacy is Not an Option - Undead Update

The new free story expansion allows the player to turn undead and gather a metal band – literally – over the course of six new missions, built upon the unique specifics of the Undead faction. The Undead are focused on attack, rather than defense — with no walls your protection is rows of undead bodies, so get ready to amass your army. Aggressiveness as a fuel for economy: raise zombies from dead enemies and recycle them into bones — one of the 5 resources unique to Undead, or use them to create more powerful troops.
