Stealth game Styx: Shards of Darkness is due out early 2017. It had been due out at the end of 2016.
Explaining the delay, Patrick Pligersdorffer, boss of developer Cyanide, said: "With this new episode of Styx we updated our engine from Unreal 3 to Unreal 4. This update has brought so much to the Styx series, from graphical enhancements to new gameplay mechanics and features. The engine transition has required some time for our team to adapt to. We're dedicated to providing the best stealth experience possible for players, so in agreement with our publisher Focus, we are delaying the game until the first quarter of 2017."
Shards of Darkness is due out for PC, PlayStation 4 and Xbox One. There are eight minutes of gameplay in the video below.
