Surviving the Abyss, the latest in the somewhat loosely-defined Surviving series by Paradox, has been revealed. It's a deep-sea base-building game with strong exploration and horror elements, and it's coming to Steam Early Access on January 17th.
There's not much to connect Surviving the Abyss to Mars and Aftermath on the surface, other than a theme of surviving despite harsh conditions. Developers Rocket Flair Studios have admitted that they're pretty big fans of Surviving Mars, though, so they're bringing that love to bear when creating Surviving the Abyss. Perhaps an acquisition is on the cards for them as well?
In any case, Surviving the Abyss tasks you with building and maintaining a deep-sea facility in the mid-70s. Your goal is to perfect human cloning technology, then figure out a way to weaponize it. Along the way, you'll have to contend with various environmental issues, including darkness, oxygen, and power to your base, but there's more at work here as well.

While you research new technology, make the sea your own, and advance the agendas of your superiors, you'll also have to battle the flora and fauna of the sea, fending them off and using them to your advantage where you can. In that way, Abyss is kind of like Surviving Mars meets Subnautica.
That's not all, though. Something...else is out there. Something, according to Paradox and Rocket Flair, "is lurking at the edge of darkness", watching you and waiting for a chance to take you. Darkness is danger and light is safety, so make sure you don't turn off the lights, no matter what you do.
Surviving the Abyss lands on Steam via the Early Access program on January 17th. You can wishlist it right now if you want to keep up with its progress and be better prepared when the horrors of the deep lunge at your base.
