Sentinels: A Robotic Race hell-bent on annihilating all of humanity. For 100 years, Humanity has been fighting a losing war. After 20 years of maintaining a defensive line, they decided it was time to attack. Of course, it all went wrong. Now, thousands of soldiers are trapped on the very planet they were trying to reclaim.

One of these soldiers is Artemis, a young woman trained as a Raptor, one of Humanity's Elite Infantry. Originally wanting a short service period to escape her past, she got more than she bargained for when she was sent in the first wave. Now, it's up to her and the Raptors to travel the world, reclaim supplies, unify the survivors, and destroy the shield generator trapping them here.

But despite her two years of training, Artemis isn't as committed to the cause as everyone else. She only wants to get off the planet for her own personal gain. Will this conflict with her squadmates? How will others react to her past? Will she even survive that long?

One thing is for certain: With hostiles surrounding them in every direction, no one is safe.
