Indie studio Failbetter has released the launch trailer of their exploration game Sunless Sea. At the helm of your steamship through several generations you will face giant crabs, dreadnoughts, sentient icebergs and madness. But the loot is waiting if you overcome the black ocean. Players can upgrade their ship, trade or smuggle (silk, souls and other weird things), and hire unique officers. The title will be out on February 6th.
