"Most of the ocean is devoid of sunlight and inhospitable to us. The differences in pressure between the surface and even a modest depth of 100 meters is enough to turn a human into mush. That pressure, that depth, is nothing compared to the true ocean deeps," creative director Thomas Grip teased on the PlayStation.Blog. "And as if this isn’t enough, the creatures living there seem like they're from another world. Gigantic squid, luminescent fish and creatures that are all mouths and teeth are only the start. If you dive down any distance you enter into a realm of monsters."
Seems like you'll be pretty helpless then, welp.
SOMA will be on PS4 and PC in 2015.
