"When humans become lonely, they become monsters,"said Cornelia Geppert, writer and creative director of the upcoming title". "Sea of Solitude" centers on a young woman named Kay, who is lonely in a waterlogged world that is home to monsters and the unknown.
The game is already featured on EA's website, and the theme of loneliness is reiterated there. Given what unfolds in the first teaser trailer below, this seems to be a fair assessment of Sea of Solitude. "On her search to change, she soon finds out that her biggest enemies are not the huge monsters that she meets on her way through Sea of Solitude, but something way more risky". Has to find out why this happened to her, and find a way to turn back into a human.
Sea of Solitude is slated for an early 2019 release on PlayStation 4 and Xbox One. "This at the core of the story of "SOS" [which is apparently the in-house nickname for the game]".
