The Expedition Campsite
Reaching the Campsite
After the initial cutscene, you’ll find yourself in a cave tunnel. Turn the Flashlight on and proceed onward.
You’ll reach a fork. Head right from here. The left path leads to a big hole on the floor.
Squeeze through the gap up ahead, and soon you’ll be outside on a snowy cliffside.
Go right and drop off the ledge to the lower path.
Keep moving, and you’ll reach another cave entrance. There’s a fork here. The left path will lead you to an E.R.C that contains a Dream Essence. The main path continues on the right.
Turn right at the end of the path to see a gap in the wall. Squeeze through the gap.
This brings you to a strange door on the right. This one is locked from the other side. There’s a crate nearby where you’ll find a Container and a Codex Entry (Telegram Text – May 6, 1929).
Pick it up and continue forward along the main path. You’ll duck under a boulder to reach a campsite.
The Main Expedition Tent
As soon as you reach this place, turn left and go forward to find a tunnel entrance. There’s a Codex Entry (Regarding Science – April 25, 1929) here that you can grab.
Head toward the large tent in the central area of the campsite.
There’s an E.R.C that contains the Keene’s Timeglass upgrade for the Rifle, on your left as soon as you walk in. Head inside the tent to trigger a cutscene.
After the cutscene, look around the tent. Grab the Expedition Map to unlock the map of this region. There’s also a Codex Entry (To The Crew – April 11, 1929) to collect nearby.
There’s also a locked chest here. You’ll need the Sturdy Key to unlock it.
Obtaining the Sagittate Stone
Leave the tent and loop around the left side to find another Codex Entry (Endless Curiosity) on a stack of crates behind the tent.
Then make your way around the campsite and look for one of those strange doors you saw earlier. It’ll be near the area where you entered.
Walk up to the door and collect the Codex Entry (Journal – August 1929) and the Sturdy Key from the crate next to it.
Return to the main expedition tent and use the Sturdy Key to unlock the chest. Pick up the Sagittate Stone from the chest.
As you do so, you’ll get ambushed by a bunch of enemies. Take them down.
Head to the strange door near the campsite and use the Sagittate Stone to open the entrance. Head inside.
The Portal Room
As you walk in through the door, you’ll reach an area that looks like an alien temple of sorts. This area is pretty much crawling with Slitherworms, but there are no enemies here.
Walk to the other end of the room and go through the door to reach the Portal Room.
Faye will briefly appear near the Alien Device up ahead, saying that she can sense her body nearby. You’ll have to find a way to activate the Portal.
Once she’s gone, look around the large room. There are two Codex Entries (Symbols and Pods – April 19, 1929) and a Radio, along with an E.R.C Activator Pen in this area. You’ll also spot a door to the Safe Room on the right. Head inside and save your progress.
Interact with the switch on the generator to your left to turn the power on.
Interact with the Alien Device. It seems a part of it is missing, and you’ll have to find it.
When you’re ready, head through the door on the left side of the Portal Room.
Obtaining the Key for the Alien Device
Go up the stairs and enter through the door at the top.
This takes you to a dark chamber. Turn left to spot an E.R.C nearby. You can open it for another Rifle upgrade, the Keene’s Widowmaker. There’s also a Codex Entry (Stock Boy’s Letter – April 25, 1929)on the broken pillar beside the E.R.C.
Head through the door at the end of this room to reach the Crypt.
When you enter the area, get ready for a fight. There will be Slitherworms blocking your way out of this room. Take out all the enemies here to move on.
With the enemies defeated, you can take the second exit out of the Crypt.
This takes you to the Upper Storage area. Go across the bridge.
Loot the section up ahead. You’ll find a Codex Entry (Last Letter – September 3, 1929), and an E.R.C Activator Pen along with some crafting materials. But the main thing you came here for is the Engraved Pod sitting on a crate in the corner. This is what you’ll need to activate the Alien Device in the Portal Room.
Activating the Portal
The path behind you is blocked, so you’ll have to take the long way around to reach the Portal Room. Head in through the nearby door after picking up the Engraved Key.
Go down the stairs and through another door. You’ll find a Codex Entry (Motivational Note – July 14, 1929) on a crate as you enter.
Take a few steps forward to trigger a cutscene.
After the cutscene, loot the area for the final E.R.C Activator Pen. There’s a Safe Room behind you. Use it to save your progress if needed. Then interact with the door at the end of the room. This will take you to the starting area where you saw this door the first time.
From here, getting to the Portal Room should be simple. You need to go to the campsite and enter through the first door to reach the Portal Room.
But as soon as you enter the first room in the Alien Temple, you’ll have to defeat a Nightmare along with other enemies. There are refilling containers in the area, so use them to replenish your Ammo when needed.
Go in through the door once the enemies are down to reach the Portal Room. Interact with the Alien Device.
How to Activate the Portal
Use the Engraved Pod on the Alien Device. The pod will slot into place, and you now have to solve a puzzle to activate the Portal.
The puzzle is simple; you have to rotate the four pieces so that the engraving on the device lines up on all sides. Start by matching up the side with the Eye.
Then rotate the device to see the other sides and line up the engravings. The device will light up and unlock as soon as you do so.
Head through the Portal to get transported to a new location.
Continue forward till a cutscene triggers and your boat appears on the water.
Get on your boat and start sailing forward. Calvin and Faye will have a heart-to-heart during the trip.
When you dock on the other side, continue toward Faye to trigger a cutscene.
Go up the steps toward the section with the furniture. This acts as the final Safe Room of the game.
There’s a shelf in the Safe Room with plenty of supplies for you to loot. It’s time to get your gear in order before you take on the final boss. We strongly recommend bringing the Grenade Launcher and the Rifle with you for this fight.
When you’re ready to move on, step toward the gate. Head through once it opens and keep running toward Slither Prime to trigger a cutscene.
How to Beat Slither Prime
The fight against the Slither Prime isn’t about solving a puzzle. It’s about learning when to dodge and when to shoot.
The boss will jump around the arena and create tornadoes of Slitherworms that track you. You’ll want to dodge away from it
It can also create a bubble of Slitherworms to appear and shoot at you after a brief delay. You’ll have to time your dodge to avoid getting hit.
As the boss does his attacks, you’ll see a red weak point appear above its face. This is your primary target.
The boss can also spawn Slithers that attack you. Make it a priority to take them down so that you don’t get overwhelmed.
Once enough damage has been dealt, the boss will start absorbing energy from the Slithers that are floating above the arena. Shoot the floating Slithers to interrupt this.
During the second phase, the boss will gain some new attacks, including a large AoE attack that’s very hard to run away from. Apart from this, the fight mostly remains the same. Keep attacking it, and eventually, it’ll go down.
Walk toward the Altar up ahead with Faye. This will trigger the final cutscene of the game.
