Neon Winter

Neon Winter is a side quest in the Fallout 4 Creation Club content "Neon Flats".

Walkthrough
You will receive the quest after installing the Creation Club content "Neon Flats."

You will be prompted to investigate the apartment in Goodneighbor. Inside the lobby, you'll find the corpses of a cleaning crew, each wearing a Cleanroom suit. Investigate the terminal, and you'll be prompted to go to the Third Rail to find the next clue.

Inside the Third Rail, you will find the Architect's note, which will prompt you to visit the Boston Public Library.

In the library, you will have several quest markers pointing to terminals in one of the main rooms. Read the Librarian's Terminal READ_ME file. The file indicates that the different terminals in the room are numbered (1, 2, 3, 5, 7, and 9). You are do run the DECRYPT command on four computers in the correct sequence. The clues for the sequence are as follows:

1. The combination is four numbers, composed entirely of primes.

2. The combination itself is a prime number.

3. The combination is the smallest possible number based on the above rules.

Following the above rules, the correct sequence is 2, 3, 5, 7, in that order.

After running the DECRYPT command on the four terminals in the correct sequence, you will be prompted to travel to Gunners plaza for the next stage of the quest.
