Subself: Lies Deep

In a dystopian future overseen by a corporate dictatorship, prisoners are arbitrarily subjected to brutal conditions for crimes they may or may not have committed. The only hope of freedom is a deal - one simple favor in exchange for a reduced sentence. Seems like a good deal, right? Well, except that favor is a solo expedition into the depths of an alien ocean full of deadly metal-consuming algae and terrifying sea creatures. With only a suit between you and certain death. And you're probably not the first, nor the last prisoner to be roped into this deal. Good luck staying alive long enough to complete the mission.
