The Destiny 2 Lightfall Headlong mission in the campaign features a few Vex lock puzzles that require you to destroy special Harpies in the correct order.

Here’s what you need to know about getting through the Headlong mission in the Destiny 2 Lightfall campaign, including the three Vex barrier codes.

Headlong is one of the later missions in the Destiny 2 Lightfall campaign and sees you complete your Strand training with Osiris. You’ll do this by destroying a lot of Vex with Strand but along the way, you’ll encounter new lock puzzles that link to barriers that block your path. To unlock any of these barriers, you need to read the lock code made up of glowing or dim lights above the barrier from left to right, and then kill a matching combination of glowing Cation Harpies and regular Anion Harpies. Killing the Harpies in the wrong order causes them all to disappear and then respawn, resetting the puzzle lock.

After fighting through the Vex and solving their barrier puzzles, you’ll eventually end up in the VexNet training course which will test your ability to grapple around and use Strand destructively on waves of Vex – a challenging fight waits for you at the end, so we have some tips further down.

For the final part of the Destiny 2 Lightfall Headlong mission, you’ll complete a Strand training course as part of Osiris’s final training test. It’s quite easy in that you just need to use the Strand grapple to zip across the VexNet and kill some Goblins to progress. Eventually you’ll reach a circular arena with a red, rotating Vex laser grid and lots of Vex to fight over several waves. Here are some tips for getting through this tricky encounter:

  • Make sure your Power Level is close to the recommended level of 1740. If it’s any lower than 1730, you might find this a bit of a struggle, so make sure you’ve got your best gear.

  • There’s no time limit so take your time to minimize deaths. Dying resets you to the beginning of the assault course, so you’ll have to complete the grappling sections every time before you can get back into the arena.

  • Use a ranged weapon to take out the Hobgoblins as soon as they spawn. They’re hard to deal with when other Vex enemies are in the way, so deal with them early.

  • Don’t waste your Super on the first wave of Vex. Later waves feature strong Minotaurs, a Wyvern, and the final boss – a massive Minotaur – so save your Super for tougher Vex.

  • Never forget about the rotating laser grid. It moves surprisingly quickly and will kill you if it catches you out. Your Strand grapple is a great way of quickly getting ahead of it.
