Kickstarter Campaign

There are still early bird rewards available in our Kickstarter campaign.

We're off to a good start, but not in the clear yet. If the idea of a retro scifi submarine roguelike makes you tingle, help make it happen! Please consider supporting our campaign.

That's all for now, thanks everyone!

- Jarrett, Team Neptune

Release date: Mid to Late 2015
Neptune, Have Mercy.
Explore the depths of an alien ocean in a sci-fi submarine roguelike. Navigate procedural cave systems, fight bizarre sea creatures, solve puzzles, and upgrade your submarine.

In Neptune, Have Mercy, you will embark on a deep sea voyage, exploring the depths of an alien world. The game is like Insanely Twisted Shadow Planet and Ecco the Dolphin meeting FTL with a splash of Metroid.

  • Exploration - Traverse procedurally generate worlds populated with alien flora and fauna. Collect research on environments and creatures. Utilize tools to manipulate the world and open new paths.

  • Crafting and Submarine Customization - Collect materials from organisms and the environment and craft new upgrades for your submarine. Mix and match a wide variety of weapons to customize the abilities of your vessel.

  • Combat - Fight against deep sea aliens with a large array of tools and weapons. Learn how enemies react to the specialized properties of your weapons and gain the upper hand.

The Vintridge Corporation has granted a small group of expert scientists the mission of a lifetime: an exploratory expedition to Triton, the mysterious moon of Neptune.
These scientists, escorted by some of the military's top brass as well as Vintridge specialists, board a submarine and dive into the deep dark oceans of Triton.
To their delight, this new world is vibrantly alive and overflowing with riches. Around every corner, however, mortal danger lies in wait.
