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.
