Digital storytelling of the Somme
The reality of war means making difficult decisions - what would you have done if it was you? An interactive episode of the BBC Three's Our World War series puts viewers in the position of a young corporal struggling to keep the men in his section alive during the Battle of the Somme.
As in a video game, on-screen buttons appear when the viewer needs to make a decision to carry the story on.
BBC Click's Spencer Kelly looks at how the episode was made.
