Not slated to be released until 2015 for the PC and PlayStation 4, Frictional Games offers up their first gameplay teaser for SOMA.

Strange occurrences are disrupting the routines of the PATHOS-2 research facility. The radio is silent. Behavioral anomalies of the machines are increasingly dangerous, if not... malevolent. The facility is devolving into chaos. No weapons, and the only escape is practically unthinkable.

From Frictional Games, creators of the groundbreaking Amnesia and Penumbra series, SOMA is an aberrant tale of scientific inquiry and survival; an entropic exploration of synapse and circuit that wades through the delusions of human consciousness.

The last we saw of SOMA were a couple of live-action videos. I'm going to assume the live-action trailers will continue given how this game is still over a year and a half out from release.
