In 1983, the Iron Duke assaulted Empire City with one hundred iron walkers, before the Guard managed to halt his grand "urbanisation."

Today, the iron walkers are reactivating -- but at who's bequest? Is the Iron Duke's plan finally coming to bear, or is there another sinister engineer in the wings?

Emergency Response II is a thrilling two-part adventure set in Empire City (and beyond!) that you can drop into any Silver Age Sentinels campaign.

Inside you'll find a deadly race against a monster's plot, and a villain who seeks not only to increase his power but his humanity. New characters are provided, as well as details of the history of Empire City.
