I found this Trailer by chance through Unit Image CGI work. Have never heard of the company Frogware but it sure looks cool and scary.
It is a game based around Lovecraft Horror style and features supernatural elements and investigation gameplay. I am looking forward to give this a try and also experiment with their Tools for Unreal Engine if they do eventually release them.
Official Copy from their website.
The Sinking City is a game of investigation and mystery taking place in a fictional open world inspired by the works of H.P. Lovecraft.
The player steps into the shoes of a 1920s private investigator who finds himself in the city of Oakmont Massachusetts, New England. A city suffering from unprecedented floods of clearly supernatural origins. A city trembling on the brink of madness.
Some of the Update Videos showcase Unreal Engine 4 running the game.
