The year is 2702, the final remnants of humanity have been doomed to the depths of the ocean by mechanical abominations known as the Apparatus. The surface world is a wasted land plagued by the machines and a deadly Hypertoxin that rots organic matter. To reclaim their rightful home, elite squads of soldiers known as Reclaimants venture to the surface world, linking their minds in a process called Soul Synchronization to share thoughts, emotional regulation, and tactical feedback.
