20,000 Leagues Above the Clouds has been announced by Swedish-studio That Brain as a steampunk, single-player game where you fly around floating islands n the sky.
Players will trade, explore, and eventually fly around the world with others via multiplayer, as the later is being considered at the moment.
That Brain describes its game as "a bit like Baldur’s Gate meets Pirates!, with more steampunk airships."
At present, the game is in development for PC and Mac, but tablets "could be an option later on."
Here's the game synopsis straight from the website:
"20,000 Above is a game set in a world of floating islands, far up in the sky. You are the captain of an airship with its crew, on a steampunk voyage across the seven skies. You’ll find your success through missions, trading, resource gathering or piracy.
Throughout the game you will find skyports where you can dock for supplies and upgrades. Here you will meet friendly as well as shady characters presenting you with their stories. Some of them may join you on your journey. As you learn more from your conversations, you gradually gain an understanding of how this strange world is held together, and how it came to be.
You choose your own name and portrait when creating your captain. Through your actions you will also to an extent define your character’s personality – be it charming or fearsome.
20,000 Above has simple click-to-move controls with a number of added abilities based on your ship and crew. Your journey begins high over the clouds, and from your vantage point you can see ships move and interact below. When you feel ready, you progress downwards to find new adventures and greater challenges."
