Vaughn and his team of military pilots and SAS special operators are stranded decades before the extinction event. But the war never stopped.

With the help of powerful alien allies and cutting-edge tech, they battle across land, sea, space—and timelines—to stop the Necks once and for all.

As the mechanized enemy launches coordinated assaults on multiple Earths, both teams must fight across realities to reset the timeline and rewrite humanity’s fate. It’s them or us—and there’s no room for error.

Fortitude delivers epic sci-fi warfare, time-bending twists, and a sarcastic battlebot with attitude. Perfect for fans of Expeditionary Force, The Bobiverse, Live Die Repeat, and Dimension Space.
