Neon Winter

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

Walkthrough
The Sole Survivor will be prompted to investigate the apartment in Goodneighbor. Inside the lobby, they will find the corpses of a cleaning crew, each wearing a cleanroom suit. Investigate the terminal, and the player character will learn that an Institute artificial intelligence program - codename "Project S.N.O.W." - is responsible. The player is then prompted to go to the Third Rail to find the next clue.

Inside the Third Rail, one must find the Architect's note on the bar, which will explain that S.N.O.W.'s designer - the Architect - is attempting to track down the rogue A.I. and stop it. The quest will update and prompt them to visit the Boston Public Library.

In the library, the Sole Survivor will have several quest markers pointing to terminals in one of the main rooms. Read the librarian's terminal READ_ME file. The file, which was left by the Architect, indicates that the different terminals in the room are numbered (1, 2, 3, 5, 7, and 9). The player character will then need to 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, the player character will be prompted to travel to Gunners plaza for the next stage of the quest. This process can be bypassed with a +6 Intelligence check, or alternately by having 3 points in the Hacker perk.

After getting close enough to the Gunners HQ, the Pip-Boy will pick up a new signal. Tracking it, the player will be lead to a terminal inside of the generator shed on the roof of the GNN building. Using the terminal will indicate that S.N.O.W. is trying to upload itself into a body of some kind. The quest will update again, sending the player to the Electrical Hobbyist's Club to the west.

There are a few ways to enter the Electrical Hobbyist's Club:


 * 1) The master-locked front door beside the intercom.
 * 2) The rear door near some fallen crates.
 * 3) A hole in the roof, which can be reached by climbing the fallen crates.

All entrances to the building are booby-trapped, but the player must make their way to the basement door within.

The basement is booby-trapped as well, with both turrets and an assaultron laying in wait. Upon descending the stairs, the player will immediately notice a bank of computers and a synth body connected to a pod. Activating the terminal (the one near the synth body, not the one in the side room) will present the player with a message from S.N.O.W. and the option to cancel the upload. Reading the message will present a new option - ignoring the upload (thus allowing S.N.O.W. to achieve its goal) and simply making a copy of the data. Either way, the player will be redirected back to the apartment to reset the system there and restore power.

After initializing the power system, the player is now able to use the elevator to access the Neon Flats apartment. Doing so will complete the quest and allow use of the apartment's workbench.
