• This tune was recorded for the soundtrack of the online first-person shooter, Destiny. Paul McCartney's first song to be specifically written for a video game, it was released with a variety of different mixes on December 8, 2014, including a "thrash" mix.
• McCartney explained why he released his video game song as a single. "When you're writing something like 'Hope for the Future', which is custom made, it is like doing a portrait for someone," he said. "You have to use your imagination and work out what they need, what they're going to want and then what you want to give them."
  
  "Then you've got to combine those three things into something that you still think maintains integrity," McCartney continued. "So in the game you're a Guardian of the last city on Earth so that suggested to me the 'hope for the future' idea and I went from there."
  
  "Then I thought it is not just a game song," he added, "this will get played outside the game so it has got to be standalone too, you can't have references to aliens or people will think, 'What's he talking about?' So it had to have its own standalone meaning and integrity."
• McCartney told NME what drew him to the project. "I was intrigued by the intricacy of the music because in a game if you go one route a certain piece of the music plays," he said. "I know from my kids and my grandkids, they just bury themselves in a game and I don't think they've got time to listen to my music. Their agenda is pretty full with all the other stuff, you know, so I like the idea of infiltrating into their agenda."
• The music video sees Paul McCartney morph into a hologram within the game. The clip was directed by Daniel Askill, whose resume also includes the visuals for Sia's songs "Breathe Me" and "Chandelier."
