Facing Threats While Performing Daily Duties

In this game, you play as a crew member on a fishing boat where an uninvited “something” has slipped aboard. While performing daily tasks such as hauling in nets, processing fish, steering the ship, and making repairs, you must confront the threats lurking in the darkness and strive to survive.Tasks must be performed in various locations throughout the ship, so players must divide up the work to complete their missions—which means you may find yourself alone for a while, even if you don’t want to.


"Thalassomania" is scheduled for release on Steam for PC. A demo version is set to be released on October 26 (local time).
