Discover how to defend against Neptune’s hostile ecosystem. The inhabitants’ weaknesses are unique for every player and no amount of former knowledge will help you. See how far you can make it into the depths, before your equipment, or your knowledge fails you.

In The Pale Deep, you'll be playing as a series of cadets in doomed missions on board "The Diving Bell" vessels. However, with every lost cadet, you learn a little bit more about Neptune's ecosystem.

You have no weapons. All you have is a foghorn, a decoy launcher, and your research tools. There is no fighting, only distracting, scaring, and hiding.

You have a camera and a radar, but just because you don't see anything on those, doesn't mean you're safe. For example, a sudden drop in temperature could indicate a presence.

You can log everything you learn in the mission database, and you can access it any time to aid in facing familiar creatures. However, none of that matters if your equipment has buckled under the pressure, or if you've encountered something no one else has before.

Not only will we learn more about Neptune through these missions, but we'll learn how to develop better equipment. Research & Development is always making progress with the help of your missions into the planet.

The effective tactics to defend against the inhabitants of Neptune are randomized and different for every playthrough. Knowledge of this ecosystem gained through previous playthroughs or by watching others will be useless.

Deep down within Neptune, lies an ocean of water and ammonia. One day, some cadet will be the first to see it, and what lies within it.
