Destiny 2 added four Lost Sectors to the Legendary Lost Sector rotation in Season of the Chosen. These four Lost Sectors are all from the Moon, ranging in difficulty from very easy to brutal. K1 Crew Quarters sits firmly in the latter category.

On Master difficulty, K1 Crew Quarters proves one of the most challenging Lost Sectors you can run. Tons of Champions, a lack of cover, and a boost to Arc damage make this Lost Sector frustrating to run if you aren't prepared. Fortunately, that's what this guide is for. Covering modifiers and strategies, here is a complete guide to the K1 Crew Quarters Master Lost Sector in Destiny 2.

Updated September 18th, 2022, by Charles Burgar: K1 Crew Quarters hasn't seen any changes since the last time we wrote a guide, yet this season did rework Arc and gave us some new toys. We've updated this guide with current Artifact recommendations, ensuring that our loadout recommendations make countering the Champions as easy as possible.

Modifiers And Recommended Loadout

If you are more than 15 Power under the listed requirement, do not run this Lost Sector on Master difficulty. The Arc burn and Attrition modifiers make this Lost Sector brutal if you can't deal damage from cover or passively heal. Farm it on Legend difficulty instead.

K1 Crew Quarters is one of the hardest Master Lost Sectors you can run. Tons of Champions and snipers dot this Lost Sector, most of which benefit from the Arc damage burn. When you pair this with Attrition, this Lost Sector demands that you either take it slow or use Solar. Here's what K1 Crew Quarters has as modifiers:

K1 Crew Quarters Modifiers

K1 Crew Quarters Modifiers
Burn	Arc
Shields	Solar
Champions	Barrier and Overload
Attrition	Regeneration is greatly impaired. Defeating enemies may create wells of Light.
Hot Knife	Shanks have Solar shields.
Master Difficulty
Equipment Locked	You will not be able to change your equipped loadout after this activity starts.
Match Game	Enemy shields are highly resistant to all unmatched elemental damage.
Extra Champions	This mode contains additional Champions.
Limited Revives	Limited fireteam revives. Gain additional revives by defeating Champions.

Since you're fighting Fallen in this Lost Sector, expect Overload Captains and Barrier Servitors. Having good Champion counters will be necessary if you want to beat this on Master smoothly. Quite a few Solar Shanks are also present, so be sure that one of your weapons can break their Solar shields. Attrition forces you to either be hyper-aggressive or incredibly defensive. We recommend using a Solar subclass for this Lost Sector, speccing for some form of healing. If you're an aggressive player, it's possible to use Arc or Void with a good degree of success; just watch your spacing.

Recommended Loadout

Subclasses
Hunter	Gunslinger
Titan	Sentinel
Warlock	Dawnblade

Hunters should go with Gunslinger for this Lost Sector. Despite the Arc burn, your best bet is to Ignite everything to death. Caliban's Hand and/or Gunpowder Gamble give Hunters easy access to Ignite procs. We suggest using Caliban's Hand if you own it. Damage a target, throw your knife, then watch the entire area explode. You can pair Proximity Throwing Knives with Fusion Grenades to guarantee an Ignite with Ember of Ashes.

Titans that want to crush this Lost Sector should consider running Sentinel. Touch of Thunder with Storm Grenades and Heart of Inmost Light is one of the highest passive DPS sources in Destiny 2. Chuck a grenade, use Thruster to proc your Exotic perk, and repeat. You can use Lightning Strikes Twice to increase your grenade uptime, and you can run Thunderous Retort to make your Thundercrash one-shot Champions and other tough foes.

Warlocks have ample healing with Dawnblade, so that's what we're going to recommend—although you can also beat this Lost Sector with Voidwalker if you're aggressive enough. A Starfire Protocol build using Touch of Flame can easily trigger Ignites with each grenade, clearing waves of enemies with ease. Paired with Witherhoard, Champions and bosses will give you no trouble.

Weapons
Arbalest	Counters the Barrier Servitors and Solar Shanks.
Staccato-57	Breaks Barriers and breaks Solar shields.
Trinity Ghoul	Stuns Overload Champions and deals immense damage.
Lament	Hits hard, counters Barrier Champions, and heals you.
Thunderlord	Counters Overloads, deals great sustained DPS with its Catalyst, and it matches the burn.
Arc Heavies	Linear Fusion Rifles and Rocket Launchers should do great here.

Your top two priorities are countering the Lost Sector's Champions and breaking those Solar shields. Consider bringing a Solar Primary to deal with the shields. CALUS Mini-Tool, Staccato, and Ticuu's Divination are some good options. If you can, we highly recommend giving Thunderlord a try. This weapon deals great damage versus Champions and can melt the final boss with the Catalyst installed. Legend of Acrius is a good option too if you're playing an Arc 3.0 build. Ultimately, be sure you can break the Solar shields and can counter both Champion types.

K1 Crew Quarters: Entrance

Entrance Enemies

• Two Overload Captains
• Dregs
• Vandals
• Shanks
• Explosive Shanks

Stick to the rock on your right when you enter the room, never pushing forward unless the coast is clear. A few Vandals will run to a vantage point on your left, usually causing the Overload Captain to do the same. Take down the Vandals, then kill the Champion as fast as you can. If you kill the Vandals and Dregs, ignoring the Champion, you'll have to face two Champions at once.

You can stop an Overload Champion's health regeneration by shooting an Overload Round into it, even while it's recovering from a stun. Right as a Champion gets up from being stunned, fire an Overload Round into it. It won't stun the Champion, but it'll prevent it from teleporting and healing for several seconds.

When enough enemies are killed, a second wave of Fallen will spawn. An Overload Captain, Shanks, and a few Dregs will rush out from the nearby building. Once again, destroy the Overload Captain as fast as possible.

As you run into the building, throw a grenade dead center of the floor. Explosive Shanks will rush from the boxes straight into your grenade. Push forward into the next section.

K1 Crew Quarters: Pathway

Pathway Enemies

• Three Overload Captains
• Two Barrier Servitors
• Dregs
• Vandals
• Shanks
• Explosive Shanks
• Marauders
• Tracer Shanks

Directly ahead will be an Overload Captain. Stun it, then kill it from a distance. Do not push up. If you do, additional Champions will spawn. From the building, pick away at Fallen from a distance. Dispatching enough Fallen will cause more Fallen to spawn near the middle of the pathway. If you're a Shadebinder, you'll want to deploy a Bleak Watcher or two at this point.

An Overload Captain and Barrier Servitor will spawn alongside a wave of Explosive Shanks, Vandals, Marauders, and Dregs. The Barrier Servitor will make all of these enemies invincible. Damage the Servitor slightly until it deploys its shield. Once deployed, use your Anti-Barrier weapon to break it. This will remove every immunity tether from the Servitor for a short time. Use this moment to kill as many adds as possible, using Solar Ignitions or your Super to do so. If you can kill the Servitor during this part, do so. Otherwise, focus on the Servitor once it pops its barrier a second time.

Now that the Servitor is dead, direct your attention to the Overload Captain. As always, stun it before using your Heavy weapon on it. If you're using an Arc Special or Heavy, use it to kill the Captain. Push forward, but don't reach the end of the path. Three more Champions will spawn, one of which will be at the boss arena. You only need to deal with two of them: a Barrier Servitor and Overload Captain.

Just as before, you'll need to disrupt the Barrier Servitor by breaking its shield to make the nearby adds vulnerable. Do not push up while doing this, as Tracer Shanks dot the cliffside on your right; pushing too far forward will get you killed.

If you can't find a good angle to fight from, you can use the pipe at the end of the path (shown above). Kill any Tracer Shanks on the cliff before doing this. Certain slits in the pipe make for great angles to fire from. Just be careful of any Dreg grenades. When the Barrier Servitor is dead, use a Super or Heavy ammo to kill the Overload Captain and any remaining enemies. Follow the cliff that the Tracer Shanks were at to reach the boss.

You can shoot Dreg grenades before they explode to disable them.

K1 Crew Quarters: Boss Arena

Boss Arena Enemies

• One Overload Captain
• Two Barrier Servitors
• One Heavy Shank boss
• Dregs
• Vandals
• Shanks
• Wretches

A Barrier Servitor will be present on a platform preceding the boss. It will be protecting Shanks, Vandals, and Dregs. Force it to spawn its shield, break it, then kill the Servitor. Defeat the remaining adds, then slowly move up to the boss platform. You'll come across an Overload Captain, Vandals, and the Heavy Shank boss. Focus on killing the Overload Captain first, then damage the boss.

When the Heavy Shank reaches 66% HP, it will spawn a wave of enemies. This wave will have a Barrier Servitor alongside some typical Fallen adds. Kill the Servitor as fast as possible. Arc Specials and your Heavy weapon can quickly take it down. If you're using Stasis, a Duskfield or a few Bleak Watcher turrets can stunlock the Servitor, preventing it from deploying a shield. Once the Servitor is dead, it's smooth sailing. Kill the remaining Fallen adds, then damage the boss once more.

When it reaches 33% HP, three Wretches will spawn. Keep your distance, take them out, then destroy the boss. You can now open the Lost Sector chest, completing the run.
