Destiny 2's Fourth Horseman Exotic Quest Guide: How To Earn The Shotgun

The Season of the Worthy has added its first Exotic quest to Destiny 2, returning the four-barreled shotgun The Fourth Horseman from the original Destiny. It's a fairly formidable weapon, although seems a better bet in PvE content than in something like the newly restarted Trials of Osiris. You'll need to complete an Exotic quest to get the new shotgun, however, and that means going to some effort to explore the Tower. Here's where to go and what to do to get your Fourth Horseman and become death.

Update: Bungie has fixed a bug in Destiny 2 that prevented the correct Legendary Lost Sector from becoming available in the EDZ Seraph Bunker. That means you can now finish the quest to get The Fourth Horseman. Check out the full guide below.

How To Start The "In Rides A Pale Horse" Exotic Quest

To get started on your quest for The Fourth Horseman, head to the Tower and visit Zavala. He'll give you the Exotic quest "In Rides a Pale Horse," which dispatches you to a Vanguard vault to find the gun. First, though, you'll need to visit his office.

The mission marker will appear on your map, but it's not immediately obvious how to find it. You'll need to go down to a lower level to find the office, which is between the Courtyard and Bazaar sections of the Tower. Find the corner next to Banshee's desk for a staircase that will lead you down. You can also jump off the bridge heading toward the Bazaar, but that's a little more difficult to do.

Zavala's Office

Continue down the stairs to find a lower bridge, then head toward the Bazaar side to enter Zavala's office. It's big and gold, so you'll know it when you see it. There's a staircase on the right side that will lead you to the Vanguard vault, but the door is closed. You'll need to find a secret way in.

When you get to the vault room, turn around and look at the stairs you just came down. Crouch and slip underneath them to find a vent you can enter. Follow it until you drop down, then jump over the gap and take the stairs. You'll enter a hallway with a ramen vending machine. Hang a left and look for another vent you can climb into above you.

From here, continue forward to the end of the path (don't take the right turn that'll drop you down) to exit this vent into another staircase. Follow it toward a pile of crates, climb back into the ceiling, and look for the hole you can drop out of to get into the vault. Unfortunately, The Fourth Horseman is already missing.

Missing In Action

Return to Zavala, who's upset someone stole the gun and slipped in under Vanguard security. He'll send you to Ana Bray in hopes of figuring out who took The Fourth Horseman. Head to Mars's Braytech Futurescape and talk to Ana next.

It seems the Cabal might be responsible, but you need intel to proceed. Your next job is to kill Cabal and to complete public events on Mars.

Your best bet is to fire up Escalation Protocol, as killing Cabal enemies is going to take a while. It looks as though the requirements for enemies killed is at least 300 or more, so doing activities like Lost Sectors isn't going to get you much in the way of progress. It'll take more than one complete Escalation Protocol run to complete the quest, though, so get ready for a long haul. When you're done, return to Ana.

In The Shadows

It seems Calus is involved, as are his "Shadows," the secret assassins he employs. Ana says Calus has double agents in the Red Legion. Take to the wilderness again and kill Cabal Psions and loot Cabal chests to advance the quest.

You don't need to stay on Mars for this one, so it's a good idea to try your luck somewhere less crowded, like the EDZ or Mercury. Cabal chests in the world are good for a big boost to your quest progress, so equip a chest-finding Ghost shell such as Eris Morn's Shell for best speed. You'll get anywhere from 10%-20% per chest--it seems weirdly variable--and only 2% per Psion.

Complete your intel-gathering and you'll be directed to speak to Benedict 99-40, the weird sweeper frame that's actually a secret Calus agent. You'll find him in the Annex portion of the Tower, so make your way there.

Under Our Nose

It seems Calus sent a Shadow to snag The Fourth Horseman to kill members of the Red Legion, but the Shadow was killed. Apparently, there's some family drama between Calus and his daughter, who intercepted the gun. To find out more, you'll need to kill more enemies.

Fly to the EDZ next. You'll need to kill enemies, complete patrols, and do public events to advance further. Grab some bounties and go nuts.

This one's a bit of a grind. You'll only get about 12% progress for completing public events (although it doesn't seem like Heroic adds anything, so don't bother doing the tougher versions), 5% for completing patrols, and much less than 1% per enemy killed. Thus, publics are your best bet, and if you can pick up some easy patrols while you do them, all the better.

When you're done, return to the Tower to speak to Benedict once again.

Rein It In

Benedict tells you that Calus figured out where The Fourth Horseman is: the EDZ (again). You need to complete The Quarry Lost Sector on Legendary difficulty, which is only available through the EDZ Seraphim Bunker Bunker.

Bungie reported that Destiny 2 was suffering from a bug that changed which Legendary Lost Sector was available today--it was supposed to be The Quarry, but for a few hours after the weekly reset, it was Skydock IV. The Quarry is now available and it's possible to finish the Exotic quest and earn The Fourth Horseman.

Legendary Lost Sectors have a suggested Power level of 1,000, and they can be pretty tough if you haven't upgraded your Seraph Bunker to allow for things like the Valkyrie or Heavy Frames to help you in battle. You'll want to bring Anti-Barrier and Unstoppable mods to deal with the champions you'll face in The Quarry. If you're underleveled, recruit a couple more Guardians to give you a hand.

Complete the Lost Sector and you'll complete the "In Rides a Pale Horse" quest, unlocking The Fourth Horseman immediately. Enjoy the fruits of your labor becoming a pestilence on the Crucible.
