Destiny: Rise of Iron – how to unlock the Sing the Iron Song achievement using the bells in the Iron Temple

Here's exactly how to get the hidden achievement.

The Iron Temple in Destiny: Rise of Iron is home to a collection of bells.

Their purpose was figured out yesterday – use them to play the Rise of Iron theme for a secret achievement.

That's all well and good, but if you're tone deaf, you're going to need more than that.

Luckily, Reddit has come to the rescue with a handy guide on which order to play the bells

You'll need at least two people to carry this off as one of the bells is in a separate part of the temple.

Just follow the screenshots here to play the tune.

One redditor confirmed that they unlocked the achievement using the guide.

“I did it with a fireteam of four. The order: 1,2,3,1,5 – 4,3,2,3,1 You will hear a sweeping sound effect while you're playing it near the end of the song if you did it with the right timing.”

So have at it!
