When a deadly alien invasion turns against Battalion 1, Captain Corban Rhodes and his team will have to summon all their grit and resources just to stay alive, but that's the least of their worries.
With the Battalion 1 project suffering continuous malfunctions and setbacks at every turn, the battalion will face its greatest challenge from within their own ranks. Is someone in Battalion 1 a traitor to the cause, a dangerous psychotic killer, or just another tragic victim of this disastrous experiment gone wrong?
Battalion 1 will have to dig deep and pull it together to save the galaxy from an unwinnable war looming on the horizon. With everyone in the battalion barely keeping their sanity, they will have to depend on each other more than ever when they face their biggest test of loyalty and maybe pay the ultimate price just to live long enough to fight another day.
