Louise Blain looks as gaming music in a post-apocalyptic world and talks to Bear McCreary about his score for the God of War series. The programme includes music from Alexei Omelchuk's 'Metro Exodus', Jesper Kyd's 'State of Decay' and Jessica Curry's 'Everybody's Gone To The Rapture' with a musical nod in the direction of Tom Clancy as well.
