EveryDestiny 2Episode comes with an opening mission that introduces the story, featured location, and a bit about the mechanics we’ll be using to grind loot. While Episode: Heresy follows that pattern, it chooses to change things by dividing the opening into two missions rather just one.
The first opening mission, Espial, gets us into the Dreadnaught, far away in Saturn’s orbit. The second sets the stage — and stakes — for the first Act of the Episode. Befitting our return to the eldrich horror that is Oryx’s flagship, things get dark, and quickly.

How To Complete The Espial Mission
Espial is the shorterof the two introductory missions in Heresy, and you’llspend most of your time on your Sparrow or Skimmer.Follow these steps to progress:
How To Defeat Gorkall The Gatekeeper
Gorkallis a boss-levelTaken Ogre with two phasesseparated by an immunity phase. You candamage itwith whateveryour best DPS optionis. Linear Fusions, Outbreak Perfected, and otherprecision damage weaponsare best, so long as you hit Gorkall’s crit spot in its eye.
Keep at ground levelfor this fight, as Gorkall’seye beamscan easilypush you off high platformsor into other unfavorable positions.

At50 percent HP, Gorkall will gain animmunity shield, andthree more riftswill appear. Thefirstis in the airabove the boss, and theremaining twoare oneither side of the arena.
Gorkallwill bevulnerableagain when youdestroy the last rift. Therearen’t any more mechanicsto deal with, and you canchunk the boss’s healthbar with whatever you have ammo for.

Gorkall’s deathopens the Taken anchorportal in the back right of the arena. It’s time tohead to the Dreadnaught.
How To Complete The Recce Mission
Recceis a much longer mission. Youstartit as soon as youenter the portalin theTaken anchorin the EDZ. Thefirst partis a lengthyplatforming challenge.
You’ll be on theDreadnaught properonce you make itthrough the portal.ForDestiny 1veterans, theplace should be familiar, as the basiclayout of the level ismostlyunchanged. There are, however, lots of tentacular growths…growing from many of its chitinous surfaces.

Proceedup the staircaseto the left of where you entered andkeep left through the opening. Make your waythrough the hallwaysand a few Taken until youreach the huge chasm. Hop across it using the now conveniently placed bridges andthrough the opening in the far wall.
Thepath through the broken left-hand wallis still present, so ignore the Taken at the end of the hall and head into the smaller tunnel.

Follow the pathuntil you enter acutscene with Eris and the Drifter, where things get more than a little desperate.
When you regain control of your character,head across the chitin bridgesand up to your right,past the orange-bar Ogres. You can jump across the gap beyond the second Ogre if you have an Eager Edge Sword.

If youdon’t have a Swordhandy,keep rightuntil you reach the starting area of the King’s Fall Raid. You’ll know it when you see thelarge hallway with six Hive totems. Head down the hallway to reach the ritual site.
How To Beat Felghul The Requisitioner
As soon as youreach the ritual site, thesecond boss encounterof this mission pair starts, this time againstFelghul the Requisitioner. The fight takes place acrossthree immune phases.
Felghul is aboss-level Taken Knightwith a smaller health pool butplentyofhelp from trash mobs. He’llgo immune at two-thirds health, and you’ll need todefeat two Barrier ConjurerTaken Centurions to drop it.

You’llrepeat the processonce more when you’ve done66 percent of the boss’s health. The rough part ishandling all the mobs, especially since the enemies in this encounterspawn infinitely.
Do damagewhenever youfind an opening, and once Felghul finally dies,grab the Tablet of Ruinartifact underneath the platform. From there,continue away from the ritual siteacross the bridges.

How To Complete The Final Encounter
Head through thegreen-tinted hallwayin the distance andfollow it to the rightand around through the Hive tunnels. You’ll eventuallyreach a room with huge Taken eyeseverywhere, giving you theSuffocating Terror debuff.
Turn immediately to yourright and drop downwhen you see the eyes, as thedebuff will kill youwhen it reachesten stacks. Thelower level is outside the eyes' gazeand where you need to go to reachthe end of the mission.

For thefinal encounter,you need todestroy the Pyramid structuresbyshooting the Taken Blightson their surface. The Blights appear in this order:
Whenall the Pyramid structures are dealt with, approachEris and Drifter, lying near the backof the arena, for one of the moreemotionally gutting Destiny 2 cutscenesin recent memory. There’s also a neat surprise at its end.
