Frictional Games just updated their deep sea, psychological horror game, SOMA, with Tobii eye tracking support.
In SOMA, there is no fighting back; either you outsmart your enemies or you get ready to run. But, what happens when your own body betrays you? With the addition of Tobii eye tracking, you become part of the controller, the dread and anxiety pressing against your actions and threatening your resolve.

To celebrate this rather unique update, Frictional Games is running a big sale on Steam. Not only is SOMA going for 66% off, but you can get 80% off of the Amnesia Collection, Amnesia: The Dark Descent, Amnesia: A Machine for Pigs, and Penumbra.

For a quick refresher, be sure to read up on our review of SOMA. If I recall, I found it to be one of the best games of 2015.
