UNRELEASED GAME – VAPORWARE
This game is stuck in the development limbo known as Vaporware. Few to no details have been released about about its gameplay, plot, or release date since its announcement many years ago. It may or may not be in active development, but neither has it been cancelled officially.
Deep Down is a single-player game with the option to have up to four players in co-op multiplayer, akin to that of Dark Souls, with random players dropping into the player's world to help them defeat monsters and find artifacts. Deep Down begins in New York City in the year 2094. By touching magical artifacts, players are teleported into the distant past to explore dungeons and avoid or battle monsters and seek treasure. Each of these dungeons are randomly generated for each player. As well as this, the artifacts you touch correspond to an emotion, including anger, rage, hate, envy, lust and wrath.
It was announced for PlayStation 4 in 2013, but entered development hell and, despite being near completion, was not released. In early 2015, Kazunori Sugiura stated in an interview with 4gamer that the vision for the game had expanded since its initial 2013 reveal, to better appeal in the long term to players, and so the development timescale had been extended. In September 2021, former chairman of SIE Worldwide Studios Shawn Layden stated that he had "no idea" what happened to Deep Down.
