Mercenary Alex Mercer knows that humanity is change in her pocket. In 2039, ever since she was orphaned on the criminal infested, tropical island of Toppanga, twenty-three-year-old Alex Mercer searched for the answers to her past. Now she’s presented with a high-risk contract that offers a different payment – information about her parents and her past.

Alex and a group of assigned mercenaries must apprehend the elusive rogue soldier Maximillian Roivas.
As the mission progresses, Alex feels something lurking in her mind, a dark psychological entity that’s finally manifested and is vying for dominance. The presence yearns for a hunt, and it craves complete autonomy, and Alex can’t ignore the presence any longer.

When she uncovers more clues about the mysterious Roivas, she finds disturbing information about clandestine experiments by the U.S. military on vulnerable targets. Alex won’t rest until the experiments are permanently ended, whether it’s by her own volition or by a beast with an insatiable bloodlust guiding her hands.
