Legacy - the online game, the radio drama

Set in and beneath the streets of London, Legacy combines a two-part radio drama and an online adventure game to tell the story of Jules and Harry: two 20-something siblings coming to terms with their family's shocking past. Brought together by the death of their grandmother Rose, Jules and Harry uncover more than they bargained for as they seek out their inheritance, discovering a mysterious legacy left to them by their enigmatic grandmother.

You play the game as Harry, attempting to escape an abandoned bunker complex hidden beneath the streets of London. You'll need to keep your wits about you as you explore the dark underground world in which you find yourself trapped. Listen carefully and think logically to solve the puzzles and crack the codes that will reunite you with your sister, Jules. Solve the mystery of your grandmother's past and escape your unwanted legacy.

Jules's story is told through the radio drama. Episode 1 will air at 1830 BST on Sunday 22 August when the game will also be available. Making time for both the radio drama and the game will reveal further secrets of Legacy's hidden labyrinth and ultimately bring Jules and Harry's story to a conclusion.

Devised by David Ian Neville, both the game and the radio drama were written by Louise Ironside and me. Legacy is a collaboration between BBC Scotland New Media, BBC Radio Scotland and Radio 7. The game was built by independent producer, DESQ. Audio design by Nick Ryan. Find out more here.
