A complete walkthrough to this Io Adventure.
Our Destiny 2: Arecibo walkthrough guide explains how to identify the source of the transmission, follow each source of music and secure the Warmind Vault.
Before we get into the walkthrough, it’s important to note that this mission only unlocks once you’ve completed every other Adventure in Io.
Arecibo’s easily one of – if not – the best Adventure in Destiny 2 as it’s shrouded in mystery throughout and features quite a few unique surprises that you won’t find anywhere else in the game. It’s a real mixture of exploration, lore and combat which makes this Adventure a standout, although it can be a bit tricky to locate some of the objectives and survive the big battle at the end.
To help you out with this, we’ve put together a walkthrough below with a handy video link too.

Identify the source of the transmission and follow the music
When starting out, keep an eye on the minimap marker and hop on your Sparrow. Simply follow the marker and it’ll lead you into a darkened cave entrance. Proceed inside and look out for a semi hidden turn off to the left. Head in and you’ll see a few Vex seemingly entranced by a strange music box.
Show no mercy and wipe them out before interacting with the music box itself. Once you’ve soaked up the dialogue, head back out the way you came in, turn right and hop on your Sparrow. Follow the path as it leads you round to to the right and on a really long journey.
Sure enough, you’ll reach a circular drill site just past a large base of operations. Look around and you’ll see a couple of electrified Vex outside another small cave entrance. Interact with the music box inside and hop on your Sparrow again.
Follow the path to the right and through Terrabase Charon until you come to a bunch of enemies near a couple of deactivated Vex Goblins. Look to the left of the Vex Goblins and you’ll notice a narrow cave entrance. Again, interact with the music box.
Head out, immediately turn right and ascend up the slope, climb the ledge and go through the narrow rocky tunnel. This will lead you into Warmind Vault JYS-2. Once you’re in, proceed past the large drill in the center and you’ll notice the music box floating behind the glass window ahead.
Swing left and round into the room, before turning left into a horde of Vex enemies. It’s time to do battle!
Secure the Warmind Vault and follow the music
Make your way into the Vex horde and begin clearing them out. This shouldn’t be too tricky as they’re all hindered by all the music boxes in the area. When they’re down, get ready for an influx of tougher enemies, but not to worry – they’re all affected by the music boxes too.
When large groups spawn, chuck grenades and retreat to a safe distance. We recommend hitting any Vex Fanatics first as this will deal splash damage to anything nearby. Otherwise, keep hitting them all in their shiny chests and they’ll go down pretty quickly.
In the final phase, a large Vex mini-boss will appear. This is your cue to whip out your Power weapon, or even better, let loose with your Super ability. Once you’re done, follow the music down into a nearby tunnel, turn right and examine the wall to reveal one last mysterious music box.
That’s this Adventure complete!
