The Surge: Operation Enduring Unity III (Unabridged‪)‬

A year has passed since America plunged itself into a new Dark Age.

The Californian-led United Republics of America, emboldened by their alliance with the independent nation of Texas, launch the first invasion of the United States in over 150 years.

In this storm of hyper-modern war, Sophie Kampbell discovers a dark secret about her militia's corporate sponsors and their plans to unite the country...or burn it down in the process.

Despite exotic new weapons and strategies, the same heroes on both sides are called upon to make their greatest sacrifices yet, all in the name of Unity.
