How To Complete Captain Sims Quest in Atomfall
Captain Grant Sims is the leader of the Protocol military force in Atomfall, and he can be found inside the force's headquarters in Wyndham Village. While Captain Sims is a daunting figure due to how much trouble he's caused in the village and surrounding areas, you can get on his good side with a few good deeds. This effort can result in learning of a new escape route out of the Quarantine Zone, but can Captain Sims and Protocol really be trusted? We'll go over how to complete the entire Captain Sims investigation and the ending it gives you in Atomfall in the full walkthrough below. Finding and speaking with Captain SimsFirst and foremost, you need to speak with Captain Sims to get started on his investigation. As soon as you enter Wyndham Village in Atomfall, you'll be instructed by the Protocol soldiers to go and talk to the captain at the Village Hill location. This is found in the center of two, just north of St. Katherine's Church. Inside the Village Hall, you'll find Captain Sims standing behind his desk at the end of the first room. Talk to the captain, and he'll initially be wary of you. However, to earn his trust, all you need to do is complete an investigation for him. You can pick between two investigations, and both take place in Wyndham Village. The first is diving into a murder that occurred at St. Katherine's Church. This kicks off the Murder in the Church investigation, which we've already covered in a previous walkthrough. This investigation doesn't take too long, and it has a couple of different endings. The other investigation you can complete for Captain Sims takes place at the local bakery. The baker's husband has been acting strangely, and the captain wants you to find out what's going on. This is another short investigation. After you complete just one of the investigations, return to Captain Sims and report your findings. This will make the captain trust you a little more, but now he wants you to look into a larger matter. Find and confront Dr. GarrowCaptain Sims now wants you to interrogate a known fugitive, Dr. Garrow. Dr. Garrow is a scientist who's responsible for the Quarantine Zone being put up, and she's locked up in the Skethermoor Prison. The doctor apparently tried to escape using a strange device, and Captain Sims wants you to find out more about what it is.We have covered how to find Dr. Garrow in Skethermoor Prison in a previous walkthrough. However, that walkthrough doesn't totally apply if you go through Captain Sims before attempting to find Dr. Garrow in the prison. Captain Sims gives you permission to enter the prison, and when this happens, you won't have to fight through all the Protocol soldiers that surround the prison. You can easily get through the prison, without the use of a Signal Redirector, and find Dr. Garrow.If you try to break out Dr. Garrow before speaking to Captain Sims, it's highly recommended to follow our walkthrough, as that will allow you to get through with much fewer issues.Either way you go about it, Dr. Garrow is located on the bottom floor of Skethermoor Prison. Keep heading straight in the prison, and you'll continue to head down different levels. Eventually, you'll find Dr. Garrow in a holding cell in the center of a large warehouse.Speak with Dr. Garrow to hear her story. You can choose to break her out of the prison if you believe her story, but you mainly want to loot the Signal Redirector in a nearby room by Dr. Garrow's prison cell. If you have the Signal Redirector, you can choose to leave Dr. Garrow or break her out, which can lead to a different ending in Atomfall. With the Signal Redirector, return to Captain Sims. Recover the Radio Part in Casterfell Woods When you return to Captain Sims again, you can show him the Signal Redirector you looted. Now, the captain lets you in on his escape plan, but he's still missing one crucial element before the escape can happen. The Wyndham Village citizens supposedly stole a key radio part from Protocol and bartered it for supplies from the Druids in Casterfell Woods. Your job is to track down and retrieve the radio part. If you have already completed some quests for Mother Jago in Atomfall, it's entirely possible you already have this radio part. In which case, hand over the part to the captain and you can proceed with the investigation. However, if you need to find the radio part, you can do so by heading to Casterfell Woods via the Sewer Tunnels in Wyndham Village or backtracking to Slatten Dale and entering the woods through there. Either way, you need to visit the Speaking Cave in Casterfell Woods, which is marked on your map if you're tracking the Captain Sims investigation. You can also find it at coordinates 23.0 E, 85.4 N.The Speaking Cave is right in the middle of a Druid camp, so you want to try and avoid them as much as possible. You also need to contend with plenty of Druids inside the cave. However, if you've completed Mother Jago quests, then you might be able

Recover the Radio Part in Casterfell Woods

When you return to Captain Sims again, you can show him the Signal Redirector you looted. Now, the captain lets you in on his escape plan, but he's still missing one crucial element before the escape can happen. The Wyndham Village citizens supposedly stole a key radio part from Protocol and bartered it for supplies from the Druids in Casterfell Woods. Your job is to track down and retrieve the radio part.

Either way, you need to visit the Speaking Cave in Casterfell Woods, which is marked on your map if you're tracking the Captain Sims investigation. You can also find it at coordinates 23.0 E, 85.4 N.
The Speaking Cave is right in the middle of a Druid camp, so you want to try and avoid them as much as possible. You also need to contend with plenty of Druids inside the cave. However, if you've completed Mother Jago quests, then you might be able to walk in without being harmed.
The radio part you're looking for inside the Speaking Cave is located at the very far end of the winding paths you'll find near the entrance. Keep heading straight until you find a large wooden structure of a deity surrounded by blue plants. Head behind this wooden man and enter a small, blue-lit cave. Here, you'll find the radio part for Captain Sims on the ground near some potatoes. You can also find an audio log of Captain Sims talking about the "Atomfall Project."
Return to Captain Sims with the part to proceed with the investigation.
Enter the Oberon Digsite

After returning the radio part to Captain Sims, you've gained his full trust. To proceed with Protocol's escape plan, you need to enter the Windscale Plant in the Interchange, find Oberon, and destroy it.
This involves entering the Interchange, powering on all four Data Room Stores, and turning on the Central Processing Unit. Once the CPU has been activated from the central room in the Interchange, a new entrance will open up that leads you straight into the Windscale Plant. Take the entrance and you'll find yourself in a new, rainy area surrounded by thrall enemies.
Keep heading straight through the Windscale Plant, trying your best to avoid the thralls and other enemies, and eventually you'll reach doors to enter the Oberon Digsite area.
When you first enter the digsite, you're greeted with a view of the Oberon meteor, which is massive and glowing purple in the center of a large cavern.
Destroy Oberon and escape with Protocol

Now that you have entered the digsite, it's time to blow it to smithereens. To do this, head toward the Oberon meteor. Here, you'll find two robots patrolling both sides of the large rock. You might also see four cylinders with the word "Explosives" printed on a large tank at the top of them. You need to visit each one of these cylinders and arm a bomb that's found at the base of them. There are two bombs each on the left and right sides of Oberon.
Once you've visited and armed all four bombs, go back near the entrance to the digsite. On your left (if you're looking at Oberon from the entrance doors), you'll see a large building. Go towards the building and enter the hallways. Keep proceeding down the hallways, which have a few haz-mat enemies in them, and find the command center for the digsite. You'll know you're there when you see a ton of command stations and levers.
One of the levers, located on the top left side of the command center, is labeled "Self Destruct Console." If you have armed all four bombs below, pull the lever. You're now given three minutes to escape the Oberon Digsite area and the Windscale Plant before everything is destroyed.
Make your way through the Windscale Plant again, and then go back to Wyndham Village when you're safely in the Interchange. The easiest route to the village is through Data Store Room A. In the village, go to the Village Hall to find a note left behind by Captain Sims. He states that Druids attacked the village, and Protocol retreated to Skethermoor.
Go to Skethermoor, making sure to follow your Captain Sims quest marker, and you'll find the captain ready with a UK-themed chopper right next to the prison. You can talk to the captain, board the chopper, and then escape the Quarantine Zone.
Atomfall ends as soon as you get on the chopper.
