Sam's got a lead on the cure for the zombie virus.
But to get the cure, Sam has to do something that doesn't come easily to him. He's got to follow orders from Garret, a no-nonsense, by the book commander who isn't impressed with Sam's customer support skills or his lack of discipline. But can Sam and Garret work together, when Sam does anything but follow the rules?
To find the cure, Garret and Sam need to infiltrate a Zombii Co. factory, but the factory contains more secrets than just the cure. It contains Zombii Co's other experiments with zombies and an insane manager willing to do anything it takes to keep those secrets where they belong, including infecting everyone in the factory with the zombie virus.
When Sam's mission goes sideways, he has to fight his way through acid spitting zombies and super zombies while working with Garret to keep his unit alive, and keeping all of them uninfected.
If Sam doesn't get his act together, he could lose his friends.
Worse...
He could lose the cure that can save the world from the zombie apocalypse
