Activating the Containment Sector Shuttle

The next SCU that you’ll have to activate is in the Containment Sector. You can reach the area via Waterworks. First, head to the eastern Safe Room in the Waterworks zone.

From here, you have to head to the area shown in the image above. It’s a straight sprint through the zone. There are a few monsters along the way, but you should be able to take them down easily.

Once you’re here, you’ll have to activate the panel to the right to bring down the platform.

Then walk across and up the stairs to reach a second panel. Use it to lower the dam blocking off the water.

Return to the first panel and activate it to open the path to the right below. Then go down the ladder.

Continue head forward along the passage, and you’ll soon enter a radiated area. The Containment Sector is just beyond this point.

After going up the ladder, you’ll receive a transmission from Soldier C-12 warning you about the radiation. Head into the Safe Room on the right. Save your progress here.

Leave the Safe Room and go left. There’s a path to the left up ahead. But first, you’ll want to go all the way to the end of the passage straight ahead and through the door on the right.

As you go up a staircase, you’ll see a section through a circular doorway. Ignore it for now, and continue running straight to the right.

You’ll have to fight two Infected Workers up ahead. One of them has a shield.

Use the panel past the enemies once you take them out to activate the Shuttle for this zone.

Obtaining the Radiation Mod

Suit Mods are equippable upgrades that offer passive bonuses. These are typically found behind Vaults that you’ll need to use Vault Keys to open. Each zone has a Vault, but these are hidden well and require thorough exploration. While these Mods are optional, the Radiation Mod is the only mandatory one required to complete the game.

Since the Containment Sector is heavily irradiated, we will have to grab the Radiation Mod before we can venture deeper into the area.

Return to the first area after the Safe Room and go along the passage to the left.

Keep moving forward until you reach the exit to Factory East. Pick up the glowing item near the body to collect the Basement Keycard. The nearby panel will extend the bridge, creating a shortcut to Factory East.

Go across the bridge and activate the lever to open the big door on the other side. Head through the door.

Stick to the main path and keep heading left. You’ll run into another Security Turret encounter. Defeat the enemies to unlock the doors.

Keep running left until you reach a ladder heading down past a doorway. Go down the ladder.

Go right now until you reach the area where you used the Supervisor Key to enter the Waterworks. Head down the staircase and then down a ladder.

Go down a bit to find a door that opens with the Basement Keycard.

This will take you to a combat room where you’ll have to fight a Husk Brute along with four Infected Reactor Workers. Kite them around and take them out.

Enter through the door on the left to find the Radiation Protection Mod. It requires 4 Energy Cells, but if you’ve been exploring the areas that you’ve completed, you should have enough to equip it.

You can equip the Mod from any Restoration Pod you’ve unlocked. This will allow you to move through the radiation zones without taking any damage.

When you’re ready to head back, use the Shuttle in Factory East to fast travel back to the Containment Sector.

Reaching the Second Safe Room in Containment Sector

From the Shuttle room in the Containment Sector, go left until you reach the large circular doorway and head in. Then head through the open doorway to the left.

Go up the passage, and you should spot a Burster walking in from the other side. Take it out from a distance. These enemies like to run up to you and explode. Head into the room to the left.

You’ll find a Husk and two Glowticks to the right. Take them out and then go through the door on the bottom left.

There are a bunch of enemies in the large room, including a Spitter and a Burster. Spitters are ranged attackers that spew corrosive acid at you. Take out the enemies. Then go up the ladder on the left.

Keep running forward until you can unlock a shortcut back to the room through the circular doorway. Use the lever on the wall to the right to open the door below.

Go down the ladder and through the door. You’ll soon reach a long passage overlooking the sector. Go up along the passage through the door at the other end.

As you go down the stairs and enter the next room, you’ll encounter an Armored Mass. These enemies are big and take no damage from the front.

Wait for it to charge at you and dodge away so that they hit the wall. Then loop around it and attack its back until it goes down.

After defeating the enemies, go up the passage and in through the door on the left. This brings you to an elevator. Use it to go down.

The lower section of the Containment Section is dark. There’s a door to the left after getting off the elevator.

Head through the door and continue until you reach a room full of Glowticks. Take them out.

Continue past the enemies, and you’ll soon reach a locked door. There’s a ladder nearby. Climb up the ladder.

Go up the stairs to the top and through the hole in the wall.

The second Safe Room in the Containment Sector will come up on your right. Head inside and save your progress. Also consider stocking up on ammunition. The area up ahead can get dicey.

Obtaining the Grappling Hook

Head through the door on the left after leaving the Safe Room. Go down the steps, and you’ll encounter a Corroder.

These are just as resilient as Husk Brutes. But they are mostly ranged attackers with a grab attack as well.

Take out all the enemies in the area. You’ll see a radiated path heading right. Go along this path and through the door up the stairs.

You will fight a Latcher and a Spitter in the next room. Take them out, go up the stairs, and through the door up ahead.

The floor is broken in the next room. Jump down to the section below to trigger a combat gauntlet.

There are multiple Spitters, Husks, and a Corroder that you’ll have to defeat in order to progress.

You’ll spot a door to the right after defeating the enemies. Head through.

This is where you’ll find the Grappling Hook. You can use it to pull yourself across gaps using anchor points, or pull down extendable ladders.

Leave the room and use the Grappling Hook to pull down the ladder nearby. Then go up and through the door to reach a control room.

There’s a Note here that you can scan. Leave through the door on the right.

The door on the right requires the Containment Service Key to unlock. Go up the stairs and use the lever to activate two Anchor Points. Use your Grappling Hook to jump across the gap.

This brings you back to the upper section of the room through the large doorway.

Retrieving Map Data for Containment Sector

From here, run back to the room where you encountered a Spitter for the first time. Use the anchor point in the bottom-left corner to jump across.

There are a bunch of enemies here you’ll have to take down. Go up the stairs near the door when you’re ready.

Head through the doorway above to find the terminal where you can retrieve the Map Data for the Containment Sector.

Reaching the Third Safe Room in Containment Sector

Leave the room and go back down the stairs. Then follow the passage heading up, below the stairs. You’ll take some damage from the corrosive fumes.

Grapple across the gap in the next room and take the door above you to the left.

This path will lead us back to the area where we fought the first Corroder. Go all the way to the left and use the Grappling Hook to extend the ladder above you.

Go through the hole in the left wall to reach a highly irradiated area. The left path unlocks a shortcut to the eastern side of the Reactor zone, but you’ll have to get past a difficult Security Turret encounter. For now, you’ll want to head up, through the radiated section. One of the Infected Reactor Workers will come alive, so watch out for that.

Go up the stairs all the way through the door at the far end to the left.

Take out the Infected Reactor Worker up ahead and continue forward.

This brings you to a puzzle room where you have to arrange the bridges in a certain order to progress. Start by activating the panel on your side and go across.

Then activate the panel on the upper part of the platform to activate the second and third bridges. Walk across the bridge marked in the image above.

Activate the panel shown in the image above to retract the third bridge. Go up the stairs, drop off the ledge, and go forward. We’ll return here later again once we activate the anchor points.

The third Safe Room for this zone will be through the door on your right. Go inside and save your progress.

Activating the Anchor Points

Take the door opposite the Safe Room to reach a long bridge. As you go across the bridge, two Armored Masses will spawn from the opposite sides. Take them out.

This will unlock the doors. Head through the door to your left. Continue up the stairs and take down the Corroder at the top. Note the deactivated anchor point on the other side of the gap.

You can activate the anchor point using the panel just past the Corroder.

Grapple across, take out the enemy, and then shoot at the body on the edge of the railing to find the Containment Service Key. Pick it up.

Drop off the ledge and then go up to the panel. Then head through the hole in the wall to your right. This will lead you to an area overlooking the bridge room. Use the panel to activate the anchor points below.

Go down and then up the staircase.

Use the elevator at the end to open a shortcut. From here, you can sprint back to the third Safe Room in the bridge area.

Accessing the Lower Section of the Containment Sector

When you’re back at the bridge room, walk across the second bridge and activate the panel. It should retract the second bridge and extend the third one. You’ll have to go around and drop off the ledge again.

Then use the Grappling Hook to zoom across to the other side. Go down the ladder.

Continue across the bridge and take out the enemies up ahead.

In the next room, you’ll have to grapple across the gap.

You’ll see a bunch of Glowticks in the next room. Take them out and then shoot at the body above you. You’ll find an Energy Cell here. Grab it and then head through the door to the right.

Go past the corridor to a room where you’ll have to fight an Infected Reactor Worker along with a bunch of Glowticks. Take them out and go up the ladder.

Drop off the ledge and use the lever shown in the image above. It can be easy to miss. This activates a bridge in the lower floor.

Drop off the ledge and then go across the bridge to the other side. Climb up the ladder.

Use the lever next to the left door to open a shortcut back to the previous area. Then walk up to the ledge and use your Grappling Gun to pull the lever on the other side of the gap.

This will extend the bridge, allowing you to get across and through the door on the right.

Continue following the path. You’ll see a cluster of Glowticks entering through the roof of a containment tank. There’s an elevator nearby that will open a shortcut close to the second Safe Room. Now is a good time to refill your ammo and save your progress.

When you’re ready, head down the stairs and through the broken wall to trigger the boss fight for this zone.

Radiation Host Boss Fight

The Radiation Host boss fight can be tricky, but it’s not necessarily difficult. The boss has a large health pool and is covered in Glowticks that heal up any damage you deal to it. This can drag out the fight as the boss’s healing outpaces your damage output early on.

The good thing is that the boss doesn’t have many attacks to hit you with. Occasionally, it will send out Glowticks that you can one-shot using your Knife. It also has a charge-up attack that creates a radiation zone where you’ll take damage. And if you get close, it can do a melee attack, but its slow movement doesn’t make it much of a threat.

The key strategy for this fight is to use your Grappling Hook to pull out the Glowticks and take them out using melee. Keep repeating it until the Glowticks disappear. With the gone, the healing factor also goes away.

From this point, it’s just a matter of keeping your distance and shooting at the boss until its health bar drops to zero. The boss is extremely slow, making Grenades an excellent tool for this fight.

Pick up the Vault Key once the boss is defeated. Then open the door to the right and head through.

Go down the ladder and through the passage to reach a corridor. You can see the door to the next SCU just up ahead. Use the panel to unlock the door and head inside to activate the SCU. This will trigger another cutscene.

Once that’s done, you’ll receive a transmission from Soldier C-12 telling you that the Central Elevator is operational.
