Indiana Jones and the Great Circle: A Study In Fear Fieldwork Walkthrough

A Study In Fear is a Fieldwork mission that becomes available very late in Indiana Jones And The Great Circle. If you've been hoping to explore a ruin filled with deadly traps, this is the mission for you. It also introduces a temporary companion, Annika Lund, who you'll have to work together with in place of Gina if you want to survive.

This Fieldwork does have a few enemies, but it's mostly about puzzle-solving; considering that it opens up right before the game's climax, it could make a great low-combat quest to warm up with, or a treat for the postgame once the credits have rolled.

How To Start A Study In Fear

Once you complete the Hidden Pyramid in Sukhothai, your next objective is to speak to Sunan to find the location of the final Great Circle site. However, Gina will mention that Pailin is also looking for help. Talk to her at any point before you go to Wat Mahathat to find the Stone

to start the mission.

Remember, Pailin's house is directly across the bridge

from the Village dock and Fast Travel post, on the second floor.<script> window.adsNinja = window.adsNinja || {}; window.adsNinja.queue = window.adsNinja.queue || []; window.adsNinja.queue.push(function(){ window.adsNinja.queue.push(function(){ var fallbackContent = ` <video> <source src='https://video.thegamerimages.com/2024/12/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959.mp4' type='video/mp4'> Your browser does not support the video tag. `; try{ var result = window.adsNinja.monetizeVideo('.emaki-video-player-c13cf4f90fd8a224', JSON.parse(`{\"name\":\"Instream-InContent\",\"groupName\":\"content\"}`), JSON.parse(`{\"trackingId\":\"in-content\",\"playlist\":[{\"title\":\"Indiana Jones And The Great Circle A Study In Fear Location\",\"description\":\"\",\"length\":\"3:44\",\"mimeType\":\"video\/mp4\",\"url\":\"https:\/\/video.thegamerimages.com\/2024\/12\/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959.mp4\",\"thumbnailLink\":\"https:\/\/static1.thegamerimages.com\/wordpress\/wordpress\/wp-content\/uploads\/wm\/2024\/12\/20241220214131_1.jpg?fit=crop&w=1024&h=576\",\"textTracks\":[{\"kind\":\"subtitles\",\"label\":\"English\",\"language\":\"en\",\"url\":\"https:\/\/video.thegamerimages.com\/2024\/12\/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959-1735509256.vtt\",\"default\":false}]}]}`)); if(!result){ console.warn('Failed to load AdsNinja video player.'); document.getElementById('emaki-video-player-c13cf4f90fd8a224').innerHTML = fallbackContent; } } catch(error){ console.warn('Failed to load AdsNinja video player.'); document.getElementById('emaki-video-player-c13cf4f90fd8a224').innerHTML = fallbackContent; } }); }); </script>

Pailin will ask you to investigate a digsite to the south that Voss' men are using explosives to quickly excavate. Once you're ready, take the boat south past Aran's treehouse, keeping to the western edge of the map until you come to a dock with a radio but no Fast Travel sign.

Head straight into the ruins and take a picture of the Exploded Opening in the ground at the rear. There are no enemies here, so there's no need to be quiet or slow. Jump down into the hole and follow the hallway into the Khmer Vault. At the back of the room, turn the handle to the right of the demon carving to enter the hidden area below the ruins.

At the bottom of the chute, squeeze through the hole in the wall to the left of the spiked wall to trigger a cutscene, where you'll meet Annika.

How To Open The First Door With Annika

Annika is looking for the legendary tomb of a demon that's said to be buried in these ruins. After the cutscene, start by turning around and using the Lighter to burn the bundle of straw on the wall. This will reveal another handle; turn it to start the hydraulic system that powers the door mechanism.

Annika will show you a key that she found at this point; take it from her and place it in the pedestal to the left of the door.

How Do The Khmer Vault Keys Work?

You'll see several of these pedestals throughout the ruins, so it's a good idea to learn how they work right away. Once a pedestal has power from the hydraulic system in its room, the concentric wheels on the top will start rotating rhythmically. All the wheels turn at once, unless a key is inserted.

When a key is placed in the pedestal, it locks the wheels with symbols that match the key. Any other wheels will continue turning. By stopping and starting wheels with the correct timing, you need to get all the symbols on the pedestal into a single line, then remove the key. Doing so will unlock the pedestal.

The first key that you get from Annika, the Circle Key, only stops one wheel; the other two that you find in the ruins stop two wheels at once.

The first pedestal only requires that you insert the Circle Key until the Diamond and Cross wheels align with the Circle wheel. Remove the key at that point to open the door.

How To Reach The Demon's Tomb

Follow the corridor on the other side of the door to the right and through a narrow passage to a gear chamber. Once there, go forward along the ground and climb the wall at the far end. The gears ahead won't let you pass, so turn around and use your higher position to jump across the ledges on the left.

Wait for the large gear to give you an opening, then run through and jump to the platform across the gap. Turn the valve on your left when you land, then jump across the horizontal gear over Annika's head to find an Ancient Relic.

Turning the valve stopped the gears that were blocking your way, so return to the wall you climbed and follow Annika through. In the next room, pick up the Cross and Circle Key from the skeleton on the floor to the left. Use the whip to open the water pipe at the back of the room, powering the pedestal.

Use the Circle Key to align the Circle and Cross wheels, then take it out and replace it with the Circle and Cross Key to stop both at once; with only the Diamond wheel moving, it will eventually fall into line with the other two. At that point, remove the key to open the door next to Annika.

Let Annika go through the hole first; in our playthrough, leading the way caused both Annika and Indy to get stuck, forcing us to load a checkpoint.

The next room is a trap, but it's only there to scare you; the mechanism is broken, so after a few seconds the walls will stop closing and Annika will open the door, letting you crawl through and escape. You aren't in any real danger.

Once you're through, continue down the corridor to the Demon's Tomb.

How To Escape The Demon's Tomb

Approach the sarcophagus and attempt to open it; it turns out that the statues to either side are holding the lid shut. They can be rotated by turning the handles on either side of the circular platform where the sarcophagus stands

; you'll be able to see them if you climb down into the pool of water.<script> window.adsNinja = window.adsNinja || {}; window.adsNinja.queue = window.adsNinja.queue || []; window.adsNinja.queue.push(function(){ window.adsNinja.queue.push(function(){ var fallbackContent = ` <video> <source src='https://video.thegamerimages.com/2024/12/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959.mp4' type='video/mp4'> Your browser does not support the video tag. `; try{ var result = window.adsNinja.monetizeVideo('.emaki-video-player-c13cf4f90fd8a224', JSON.parse(`{\"name\":\"Instream-InContent\",\"groupName\":\"content\"}`), JSON.parse(`{\"trackingId\":\"in-content\",\"playlist\":[{\"title\":\"Indiana Jones And The Great Circle A Study In Fear Location\",\"description\":\"\",\"length\":\"3:44\",\"mimeType\":\"video\/mp4\",\"url\":\"https:\/\/video.thegamerimages.com\/2024\/12\/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959.mp4\",\"thumbnailLink\":\"https:\/\/static1.thegamerimages.com\/wordpress\/wordpress\/wp-content\/uploads\/wm\/2024\/12\/20241220214131_1.jpg?fit=crop&w=1024&h=576\",\"textTracks\":[{\"kind\":\"subtitles\",\"label\":\"English\",\"language\":\"en\",\"url\":\"https:\/\/video.thegamerimages.com\/2024\/12\/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959-1735509256.vtt\",\"default\":false}]}]}`)); if(!result){ console.warn('Failed to load AdsNinja video player.'); document.getElementById('emaki-video-player-c13cf4f90fd8a224').innerHTML = fallbackContent; } } catch(error){ console.warn('Failed to load AdsNinja video player.'); document.getElementById('emaki-video-player-c13cf4f90fd8a224').innerHTML = fallbackContent; } }); }); </script>

When both valves are turned, return to the sarcophagus and open it. This will activate the trap in the room; wait for a spike to fall from the ceiling on the other side of the sarcophagus, then pick it up and use it to smash the brick wall to the right. This will cause the room to start rapidly filling with water; equip the Breathing Device right away.

Once the water is high enough that you can swim to the ceiling, go to the upper left section of the room. You'll find a beam that you can move, causing a wall to break; the current will carry you and Annika away. Indy will automatically grab a rock in a grotto with air, letting you refill the breathing device; once it's full, dive back down and follow the current.

Squeeze through the narrow passage at the end of the tunnel, then grab Annika's hand to your right when you emerge to get pulled to safety.

How To Find The Idol Of Yaksha

Follow the overgrown path to the end, then climb the wall to your left. Walk across the moss-covered stones to the other side of the room; check the chamber to the left for an Ancient Relic, then use the whip

to swing across the two gaps to the door above where you came out of the water.

From the door, jump across to the left platform

to get a photo of the water wheel for some Adventure Points, and to find two durians to replenish any Stamina you spent while swimming.

Use the whip to help Annika climb the wall in front of the door, then team up with her to turn the handles together

and open it.

How To Solve The Burial Chamber Puzzle

Beyond the door is the Burial Chamber, where the true demon's sarcophagus is hidden. You need to activate all three pedestals to remove the statues at the center of the room. Start by approaching the demon head at the rear of the room and using the whip

to open the water pipe to the right of it.

Optionally, go to the left side of the room; you'll see the exit door, but ignore it for now and use the whip to climb the wall to the right of it. Swing across the room to reach the opposite platform and collect the Ancient Relic there.

<script> window.adsNinja = window.adsNinja || {}; window.adsNinja.queue = window.adsNinja.queue || []; window.adsNinja.queue.push(function(){ window.adsNinja.queue.push(function(){ var fallbackContent = ` <video> <source src='https://video.thegamerimages.com/2024/12/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959.mp4' type='video/mp4'> Your browser does not support the video tag. `; try{ var result = window.adsNinja.monetizeVideo('.emaki-video-player-c13cf4f90fd8a224', JSON.parse(`{\"name\":\"Instream-InContent\",\"groupName\":\"content\"}`), JSON.parse(`{\"trackingId\":\"in-content\",\"playlist\":[{\"title\":\"Indiana Jones And The Great Circle A Study In Fear Location\",\"description\":\"\",\"length\":\"3:44\",\"mimeType\":\"video\/mp4\",\"url\":\"https:\/\/video.thegamerimages.com\/2024\/12\/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959.mp4\",\"thumbnailLink\":\"https:\/\/static1.thegamerimages.com\/wordpress\/wordpress\/wp-content\/uploads\/wm\/2024\/12\/20241220214131_1.jpg?fit=crop&w=1024&h=576\",\"textTracks\":[{\"kind\":\"subtitles\",\"label\":\"English\",\"language\":\"en\",\"url\":\"https:\/\/video.thegamerimages.com\/2024\/12\/indiana-jones-and-the-great-circle-a-study-in-fear-location-1735508959-1735509256.vtt\",\"default\":false}]}]}`)); if(!result){ console.warn('Failed to load AdsNinja video player.'); document.getElementById('emaki-video-player-c13cf4f90fd8a224').innerHTML = fallbackContent; } } catch(error){ console.warn('Failed to load AdsNinja video player.'); document.getElementById('emaki-video-player-c13cf4f90fd8a224').innerHTML = fallbackContent; } }); }); </script>

To get the third and final key, go to the right side of the room and use the whip to climb the right-hand wall. Move to the right and swing to the ledge across the gap. From the top, swing to the rock with the bird droppings and climb around to the other side; you'll be able to drop to a ledge with a bird's nest, where the Cross and Diamond Key is waiting.

Use the three keys to activate the pedestals in the middle of the room, starting with the one on the right and working clockwise. Each pedestal not only removes a blocking statue, but also lets water flow to the next pedestal, powering it.

None of the keys will stop the Line wheel on the pedestals, so use the keys to stop and start the Cross, Diamond, and Circle wheels instead.

Once all three pedestals are unlocked, place the keys in their appropriate slots on the central altar, according to the symbols drawn on it:

• The Circle Key on the left.
• The Cross and Circle Key in the middle.
• The Cross and Diamond Key on the right.

When all three keys are placed, pull the lever that is revealed; the demon's head statue will reveal the sarcophagus, and Annika will claim her first archaeological find. Talk to her, then after the cutscene join her at the exit door on the left and turn the handle.

How To Leave The Khmer Secret Vault

When you land in the water, equip the Breathing Device and use it to swim through the tunnel ahead and to the left. The chamber on the other side looks like a dead-end at first; keep swimming underwater to the far end to find a smaller room that you can climb out of using the whip.

The hallway has a side door that leads back to the Burial Chamber, but you don't need to go there unless you still need to get the Ancient Relic (see above). Instead, just follow the stairs upward and take a left. When you reach the closed door, pick up the Idol of Yaksha and journal page from the ground and turn the handle to open the way back to the entrance.

There are now guards in the entry chamber; you can either fight them and go back out through the main entrance, or use the whip to swing along the ledges and reach the crawlspace near the ceiling. The latter option will reward you with supplies, including a rifle, which can be useful for getting through the digsite (which is also guarded now).

Make your way back to the dock and use the radio to call Gina (she left when the guards returned). Return to Pailin's house and give her the Idol of Yaksha to complete the mission.
