A 2011 science-fiction survival horror mobile game developed by Australian company IronMonkey Studios and published by Electronic Arts for iOS, BlackBerry Tablet OS, Xperia Play, Android and BlackBerry 10 devices.

Three years have passed since the destruction of the Marker in the first Dead Space story. Now, experience first-hand the events that unleash the Necromorph hordes once again. You'll find yourself on a mission of uncertain purpose in the Mines of Titan. Soon, however, the truth of your situation will become grotesquely clear...

Your survival is dependent on protecting two vessels - they are devices in sync, a dance and song between two entities tethered together in symbiosis. Feel edge of your seat terror where the world around you becomes quiet and numb as all that matters is the game -- that is Duet.
