Outbreak Refined is a series of quests in Destiny 2 that unlock additional perks for Outbreak Perfected. These quests are only available once you’ve completed the Asset Protection quest from Ada-1, which involves finishing Zero Hour. Each quest will require you to get kills and complete Zero Hour on Legend, but more importantly, find and activate hidden switches.

Outbreak Refined guide

Once you complete Zero Hour once, visit Ada-1 every week and collect your Outbreak Refined quest. You can stockpile all three and get them all to the same point of needing to toggle switches and then complete them in a single run. This is useful if you don’t want to run Legend multiple times.


Outbreak Refined 1 – Rapid Hit

  1. Defeat Fallen in the Cosmodrome to claim 20 Inert SIVA Clusters
  2. Toggle the first pair of switches in Exotic mission Zero Hour on Legend difficulty
  3. Complete the Exotic mission Zero Hour on Legend difficulty
  4. Speak with Ada-1 in the Tower

The first pair of switches are only available on the Legend version of Zero Hour. You may need to activate the switches and then restart the activity if you don't have enough time to reach the boss and defeat it. If you're playing in a fireteam, get one person to throw the switches while the others continue on.

The first set of switches is found immediately after the landing pad with the plane. Instead of going below the plane, enter the vents on the upper level. Drop down into the room and break into the vent behind the blue boxes. Take a left and drop down the circular tube to find two Fallen Captains.

Look for the switch on the center wall, this is one switch. To the left of the switch are red pipes, jump to them to find another switch – activating this  opens the hatch that lets you access the other switch.

From the hatch switch, turn around and jump diagonally across the room (the switch for the quest should be on your left). Go through the small tunnel that's lined with red pipes into a large chasm. Jump across the chasm and climb up the steep wall to the top.

On your left will a large "03" printed on the wall with an open hatch. Jump on top of the hatch and then jump up the tube using the notches on the wall as small platforms. At the top of the room is the switch beside the shelves. Activate the switch and then quickly retrace your steps to the center room. Activate the switch on the box to finish this step.


Outbreak Refined 2 – Rewind Rounds

  1. Defeat Fallen in Exodus Garden 2A Lost Sector in the Cosmodrome to claim Inert SIVA Clusters
  2. Toggle the second pair of switches in Exotic mission Zero Hour on Legend difficulty
  3. Complete the Exotic mission Zero Hour on Legend difficulty
  4. Speak with Ada-1 in the Tower

The second pair of switches is found on Legend difficulty, after the plane landing pad and in the long corridor after you climb up the sewer drains. Go through the air vent on the landing pad and drop down to where you activated the first switch and use the switch in the left nook to open the sewer lid.

Use the lever on the left to open the hatch, this lets you jump up into the tube. The route to the hatch is diagonal to the lever.

Jump diagonally across the room, go through the red pipe tunnel, climb up the chasm, and then use the open lid to climb up the tube. Go through the open vent at the back of the room and continue until you reach the long corridor with ledges along both sides.

The first switch is on the ledge to the right. The second one is in the distance, through the vent. The lever you find at the far side of this tunnel extends the platforms for easier traversal.

The first switch is on the right-hand side of the corridor, on the first ledge. The second switch is through the vent at the opposite end of the area. Drop down the vent and jump over the red pipes to find it on the wall.

When you fall down the vent, jump over the pipes to find the switch. Make sure you get there in time as you cannot jump back up the vent.

You can clear the enemies out first and activate the lever at the far side of the room to extend some platforms. This will make it easier to quickly get to the second switch as you only have 30 seconds to make the run. You cannot jump back up the vent to try again, so make sure you get there as fast as possible.


Outbreak Refined 3 – Headseeker

As before, these switches are only available on the Legend version of Zero Hour. You will need to know the general route through the mission, so refer to the images above if you don't know how to access the sewers via the landing pad vents.

  1. Defeat Fallen in The Devils’ Lair strike in the Cosmodrome to claim Inert SIVA Clusters
  2. Toggle the final pair of switches in the Exotic mission Zero Hour on Legend difficulty
  3. Complete the Exotic mission Zero Hour on Legend difficulty
  4. Speak with Ada-1 in the Tower

The last pair of switches is found on the slanted section of the wall as you climb out from the pipe after the landing pad and sewer/chasm area. This is immediately after the second switches.

As you can see, it's a precarious section to reach the switches. It's easier to jump down from the high switch rather than race from the one down low.

When you exit the pipe, one switch will be to your right at the very end – do this one second. The other switch is to your left, along the thin ledges and up higher on the wall, accessed by another thin pipe. Get this one first as you can then drop down to the second one.

You’ll have 30 seconds to reach the second switch, which is why you should get the one up high first. It’ll still be tough, but it’s easier to drop down to the switch.


Completing all three Outbreak Refined quests will reward you with all three additional perks for Outbreak Perfected: Rapid Hit, Rewind Rounds, and Headseeker. The ideal perk is no doubt defined by your playstyle, but it’s hard to look past Rewind Rounds, especially during raid bosses fights where ammo is scarce. Remember to level up Outbreak Perfected so you can swap out new barrels and magazine options (don’t forget the Exotic catalyst too). Take a look at our Destiny 2 Strategy Guide for more help Exotic weapon missions.
