Terminal Overload rotation and how to get keys in Destiny 2: Lightfall

The Destiny 2 Terminal Overload event is a new public activity that was added in Lightfall, and like Escalation Protocol, The Blind Well, or Altars of Sorrow, it offers a series of escalating challenges to face in Neomuna's mean streets with the promise of unique weapons as a reward. Most important of all, this event is the best way to get the Strand guns that tie into Lightfall's new subclass.

You might have noticed the event while wandering through Neomuna, only to get one shotted by a boss or an enemy—Terminal Overload has quite a high power level, so it's not something you should really consider until you've at least hit the first cap at 1750 and completed the campaign. This is also because you can't get Terminal Overload keys—the best way of getting guaranteed Strand guns—until you've finished it. 

So, here's what you need to do to get Terminal Overload keys so you can unlock an extra chest at the end of the event, and what the current weapon rotation for the event is.

How to get Terminal Overload keys

You won't be able to unlock Terminal Overload keys until after you've completed the Lightfall campaign, as well as the Welcome to the Hall of Heroes quest that unlocks after it. When you complete this you'll get the Stargazer quest from Quinn Laghari in the hall, which walks you through how to get a key and use it at the end of the Terminal Overload event. Once complete, you'll be able to acquire more keys via the same means.

There are four main ways to get Terminal Overload keys on Neomuna:

• Patrols
• Public events
• Chests
• Nimbus bounties (unlocks at reputation rank 13)

Aside from the daily bounty you can get from Nimbus once you reach rank 13, the best way to get keys is to combine those first two methods. Both patrols and public events often involve killing enemies, so are easy to complete at the same time. You also sometimes get a key from the first chest you open at the end of the Terminal Overload event itself.

Since the appeal of completing Terminal Overload is getting Neomuna's Strand weapons, I'd also recommend unlocking the Upgrade Terminal Overload key chest node with Nimbus, which is directly after the ability to get key bounties. This upgrade effectively guarantees you a Neomuna weapon when you use the key to open that second chest, so is well worth having before you start playing the event in earnest.

Terminal Overload rotation and weapons

The Terminal Overload event rotates between each of Neomuna's main districts, and depending on the district, you can grab one of three weapons from the chest at the end of the event with your Terminal Overload key. Here's each region weapon and the rotation order:

• Ahimsa Park (Terminal Overload: AP) - Basso Ostinato (Void shotgun)
• Liming Harbor (Terminal Overload: LH) - Synchronic Roulette (Strand submachine gun)
• Zephyr Concourse (Terminal Overload: ZC) - Circular Logic (Strand heavy machine gun)

One of the main draws of Terminal Overload is that it provides Strand weapons like Circular Logic and Synchronic Roulette, which can both roll with the Hatchling perk that spawns a Threadling on precision final blows or rapid final blows. Basso Ostinato also rolls with the new Destabilising Rounds perk that causes nearby targets to become volatile when you land a final blow. 

If you're currently trying to build reputation with Nimbus, remember that as of writing this, you can farm the first chest by quickly leaving the area via sparrow and returning to open it again. That said, this will likely be patched before long.
