Frictional Games is running a Soma ARG on at the moment, which is rewarding the inquisitive with image and videos related to the game.

A Twitter account called PathosII – a reference to the name of the underwater research station in which the game takes place according to the Soma Wiki – tweeted out a URL that links to a terminal users can manipulate with various DOS commands.

It is apparently the second day of the ARG, and keen players have summarised their findings so far here.

Soma was announced in October 2013 as a first-person survival horror title with an emphasis on sci-fi.

“You are not a space marine though, but a normal, and very exposed, person trapped in a nightmarish world,” said Frictional creative director Thomas Grip at the time.

“The game is by far the most ambitious and thrilling project we have ever undertaken.

“Soma is meant to be a proper sci-fi game, and to get that right we couldn’t let the themes be an afterthought,” he added.

“My favorite works of sci-fi are the ones that use fantastic worlds to probe important issues in a way that down-to-earth settings just cannot. Great sci-fi authors like Asimov, Dick and Heinlein all do this. We want to give Soma this quality as well.”

The last game from Frictional was the groundbreaking 2010 survival horror Amnesia: The Dark Descent. In 2013, it published a follow-up developed by Dear Esther developer The Chinese Room called Amnesia: A Machine for Pigs.
