Objectives
1 Follow Dani.jpg
The Callisto Protocol placeholder quest iconFollow Dani.
Follow Dani as she tells the story of the first colony in Callisto. Keep on heading in the direction she's walking until you get separated by a collapsing walkway. Find a way down going around the other walkways and using collapsed catwalks as new paths, until you get separated again.
2 New Enemy Type.jpg
The Callisto Protocol placeholder quest iconDon't make a sound.
You wake up upside down and encounter a new enemy type: The Blind. This older mutation cannot see, but is reactive to noise. Once the cutscene is over, you will have to face three of this enemy. Allow them to walk past and stab them in the back.

Follow the yellow light to L1 Maintenance. Drop down to the lower level and wait for the Blind to turn around before stabbing them.
▶How to Perform a Quick Kill
3 Stay Quiet and Low.jpg
The Callisto Protocol placeholder quest iconStay Quiet and Low.
You are given the option of going left or right. If you want to scavenge for more items, go right. The path will circle back starting area. If you crouch and slowly walk past the Blind as they emerge, you can stab them once the prompt appears. Stabbing a Blind in close proximity to another Blind does not alert other Blind.

Continue on the path and encounter more Blind. You can save your ammo and just use the GRP to hurl them onto the spikes in the room. Continue until you reach W2 Workshop. Go down the ladder and a Blind will be sleeping as you turn around. This enemy will not take notice unless you attack it first. Continue to the other side of the room and down the infested cavern.
4 Follow the Blood.jpg
The Callisto Protocol placeholder quest iconMore Blind ahead.
Descend into the cavern and try not to make any noise as this level is composed mostly of Blind, and fighting them all could drain your resources. You can follow the blood trails on the walls to find your way out of the tunnels.

You'll know you're out of the tunnels once you see the giant rock slab with the word “Caution” etched on it. Head to Tunnel 3A, use the elevated platform to get some distance between you and the 4 Blind circling the hall. Once you're through climb up the wall following the trail of blood.
5 Carry Light.jpg
The Callisto Protocol placeholder quest iconKeep moving forward.
Head straight into another tunnel system untill you reach the end where you see a slab of rock that reads “Carry Light”. A Spitter will spawn there, you can deal with them swiflty using the GRP and the spikes. Continue down the hall then climp up the ladder at the end. Head through two doors to the Access Junction.
6 Do not Engage.jpg
The Callisto Protocol placeholder quest iconHolster all weapons.
Once you reach the Access Junction area, you will find that it's crawling with Blinders. Go into the Garage to pick up the schematics for the Tactical Pistol. If you head straight for the Power Tunnels gate, you'll be disappointed to know that you can't access the power tunnels just yet - first you have to get the keycard.

Take the path right of the Power Tunnels. There are more Blinders in this area so be quiet. Go to the Transport Platform and get the keycard from by the Platform Console.
►Tactical Pistol Upgrades and How to Get
7 Locate the Power Reactor.jpg
The Callisto Protocol placeholder quest iconReturn to the Access Junction.
Now that you have the keycard you can go inside the Power Tunnel and reroute power back to the Transport Platform. Follow the cable down to the Power Station Maintenance Access. Yes there will be more Blinders down the path.

Go inside the Power Station. There will be a Reforge Station and some supplies in the room to your left. Resupply and then go up the stairs. Go to the other side of the room, following the arrows, until you reach a hole in the ground. Drop down and you'll see the sign telling you that you are going in the direction of the Power Reactor.
8 Get to the Power Reactor.jpg
The Callisto Protocol placeholder quest iconGet to the Power Reactor.
Ignore the Spitter on the way to the Power Reactor so as not to alert the other enemies sleeping in the room. Squeeze through the gap in the wall, and through the walkway where you have to deal with another Spitter and a couple of Crawlers.

Go near the light, then squeeze through another gap in the wall, then continue forward until you see the ladder by a giant fan. Climb up this ladder to reach the Power Reactor.
9
The Callisto Protocol placeholder quest iconReset the Breakers.
Breaker 1.jpgFirst Breaker
Go through the door on the other end of the room, continue on the walkway to reach the first breaker, then turn it back on. Afterwards, some Blind enemies will appear.

Breaker 2.jpgSecond Breaker
Climb down the ladder from the first breaker, and the second breaker will be directly across. There are some Blind around, but at this point, you will be used to dealing with them.

Breaker 3.jpgThird Breaker
Head right from the second breaker into the room full of spikes. Use the spikes to deal with the Blind that are circling that area. reach the end of the room and follow the arrows that will lead you to the third breaker.
10 Return to the Transport Platform.jpg
The Callisto Protocol placeholder quest iconReturn to the Transport Platform
Now that power has been rerouted. Follow the glowing power cable back to the Transport Platform. If you don't remember where the Transport Platform is, it'll be on your left as you exit the Power Tunnels. A new group of Blind will have spawned by then. You can either choose to sneak past them or stab them with the Shiv. Once you're in the Transport Platform, time to resupply because you're in for a fight.
11 Ride the Platform.jpg
The Callisto Protocol placeholder quest iconRide the Platform to Arcas.
Before you turn on the terminal, loot all 4 boxes on the platform and prepare for 4 waves of Mutated Biophages. These are the ones with tentacles who become stronger. You will have to deal with all 4 waves for the game to create an autosave for the next fight.
12 Survive the Platform Ride.jpg
The Callisto Protocol placeholder quest iconSurvive the Platform Ride
After dealing with the 4 waves of enemies, you only have a few seconds to heal and reload because the next boss fight is just around the corner. Use the crates on the platform to create cover and circle the Two-Head as it tries to attack you.

Below Enemies Encountered

The Blind

The Blind
They will make up majority of the fights in this chapter. It is best to sneak around them and perform quick kills when possible.

How to Perform a Quick Kill

Bloodworms

The Callisto Protocol Bloodworm
Bloodworms are easily dealt with using melee and guns. They make a distinct sound so it is fairly easy to spot them.

Spitters

The Callisto Protocol Spitter Lost.png
Shoot its head with the hand cannon to neutralize its ranged attacks, then eliminated it with melee attacks. Take note you can also block its ranged attacks.

Two-Head

Survive the Platform Ride.jpg
This is the last boss for this chapter. It is extremely durable and might consume most of your ammo just to take it down. Fortunately you will have lots of ammo to loot before the platform ride leading up to this encounter.

Below Tips and Strategies

Dealing with The Blinds

Blinders.jpg

Most of the areas in Below are populated with The Blind. These enemy types are reactive to sound, especially from gunfire. While you can sneak your way through this area without killing anything, it is still recommended that you take them out one at a time with the Shiv, so you have less enemies to deal with when you return to this area later on.

Platform to Arcas Fight

Arcas Fight.jpg

The Arcas fight is composed of 4 waves of Mutated Biophages. The first wave will come on your right, then on your left, the back of the platform, and then the front. It is easy to get overwhelmed as just one Mutated Biophage is enough to deal damage that will surely kill you, let alone 4. The best strategy to use is the GRP and the Hand Cannon.

In this fight sequence, you have two choices: Shoot the tentacles, or use the GRP. For the waves coming from the sides, it is best to use the Hand Cannon. For the waves that will spawn near the industrial fans, it is recommended to use the GRP to hurl them into the fan before they mutate.

Two-Head Fight

Two-Head Fight.jpg
This fight will focus more on hit-and-run tactics. Shoot either of the heads as you move around the platform. This also counts for when you are reloading. You cannot afford to stand still while you shoot.

It is recommended that you focus on one head at a time. Use pistols for long-range hits, and shotguns for the Two-Head is staggered.
