The news is slopping around the decks of the official website, under the "What's next for Outerlight?" section. But unfortunately no gameplay details or platforms were mentioned, just orders to keep an eye out for more information.
The Ship was released last year on Steam. It's a multiplayer action game that challenges you to assassinate specific targets on board a luxury 1930s ocean liner before they can get you. A bit like Titanic, but with less romance and more murder.
You have to use objects at hand to achieve your goal, and keep your intentions to yourself, otherwise the guards will pop you in gaol.
