Frictional Games have released a new trailer for their upcoming science fiction horror title SOMA, detailing the game’s story.

In SOMA, you play as Simon, a man who’s been tasked with investigating the underwater PATHOS-II research facility and its surrounding seabed and structures. The facility has been in an unusual state of radio silence prior to your arrival, with the isolation of the facility bearing down on its staff, machines beginning to take on human traits, and Alien constructions beginning to interfere with routine.

SOMA launches on the 22nd of September on PC and PlayStation 4.
