Depths of Tamil: Rift Warrior

Earth's XCU sends special forces operative Dane Tanner to the isolated swampy water world of Tamil. Tanner is tasked with a simple mission: prevent the colony's self-destruction.
Tamil, shrouded in dense mists and sprawling underwater forests, harbors secrets deeper than its murky waters. A rogue faction of genetic scientists has defied ethical norms, transforming themselves into the Riptili—genetically modified human-amphibians better adapted to Tamil's harsh marine environment.
Exiled for their transgressions, these outcasts form a hidden society in the marshes. No longer completely human, they come into increasing conflict with the surface dwellers. The aquatic rebels practice vile experiments, requiring fresh human young for their test subjects. Resentment grows, culminating in a fierce struggle.
Now, Tanner must infiltrate Tamil and make a grim determination. Can these two divergent species coexist? Or must one exterminate the other?
