In Iratus you find yourself fighting for the forces of darkness in the role of the titular necromancer—Iratus, recently freed from his millennia-long imprisonment.
You control an obedient army of the living dead, with skeletons, zombies, banshees and many other unliving warriors. Create your soldiers the only way a necromancer knows how: from the body parts of your slain enemies!
