Brain Drain: First SOMA Footage

After two live action teasers, Frictional have released the first in-engine footage of SOMA. It's first-person sci-fi horror, as expected, although there's a Giger-esque quality to the dripping carapace walls and biomechanical brain-teasing tentacles that the previous media hadn't hinted at. Story-wise, there's something unpleasant and experimental happening and it seems to involve some manner of personality transference or sharing. Gray matter has been teased from skulls and yet thinks on. I could do without the main character's exclamations of the obvious but otherwise, it all looks jolly good. The greatest fear of all is pushed to one side at the end of the trailer, when a logo dismisses the mooted PS4 exclusivity.

I'd suggest that this video contains the biggest clues as to the meaning of the final scene. I'm thinking multiple protagonists, multiple personalities or multiple bodies/vessels. Maybe all of the above.
