Outlast sees you explore the Mount Massive Asylum, an abandoned psychiatric hospital which is full of scary surprises. It costs £15.99 in the UK.
In the past Microsoft has insisted in only allowing titles on its platforms that have launch parity with other platforms, however the release of Outlast would suggest that it's starting to relax this rule a little.
Outlast has proven pretty popular on PS4 and PC and already has received an expansion in the form of the 'Whistleblower DLC', which is also coming to Xbox One.
