As big game fans, Chvrches say they got a “dream response” from Hideo Kojima after he heard their track for his new game Death Stranding.

“He said it made him cry,” Ian cook says.

The song, also called Death Stranding, is an electronic epic written specifically for the end of the game.

Band member Martin Doherty said, ” He wanted us to go and write a song in our style, something that is a typical Chvrches song.”

“Lauren worked on this theme lyrically, I think expertly, because it stands alone as a chvrches record – but it’s also closely tied to the game.”

The band was able to see the legendary Creator of Metal Gear Solid play the first part of his new game, which was released on Friday.

“It was really important to get into the atmosphere of the game and understand what it looked like and how it was,” says Ian.

“When we went to write, it happened quite quickly and quite naturally.”

It’s not the first time the band has written songs for a game, but the process for this track is very different.

“Usually it’s a few calls and each person should be satisfied. It’s not a pleasant experience, ” says Martin.

“But because kojima has creative autonomy, it was easy for him to say,’ That’s all I wanted, let’s move on.’ We enjoyed it very much.

“Personally, it’s my favorite thing we’ve ever done.”

This creative autonomy is what Newsbeat witnessed during the filming of our documentary Death Stranding: Inside Kojima Productions.

Martin and Ian were fans of the Metal Gear series long before Chvrches even formed. For the record, Metal Gear Solid V: the Phantom Pain is their favorite.

However, for vocalist Lauren Mayberry, everything was completely new.

“I wasn’t a gamer growing up,” she says. “Sometimes I find this world quite difficult to understand or non-native.

“This game looked much more human than normal games. It encourages connection, community and working together on something and thinking about the wider world.”

With only a few dates of their current tour left, Death Stranding will be the band’s last song in 2019 – but a new album is in development.

“We’re definitely doing it, I think it’s been agreed,” Lauren tells us.

Fans can stay in suspense though

“I think trying to find a balance for life as well as obsessing about the band is fine – very, very important at this stage of our career,” Martin says.

Assessing when we hear something new, Lauren tells us, ” Not two months, not six years.”
