How To Easily Decrypt Fallout 76 Nuke Launch Code In Under 5 Minutes

Fallout 76 doesn’t have a proper endgame – not at the time of writing, at least. Instead, what the game builds up to is the possibility of being able to launch a nuclear bomb of your own. If you’ve been playing the game for a while, you might have noticed that players tend to flock to ground zero as soon as a nuke is set off. Every nuke spawns a multitude of high-level enemies that can be killed for high experience and item returns. It is the best way to speed up your grind.

You can join other players as they team up to launch a nuke and let them do the heavy lifting earlier in your playthrough, but there’s no better feeling than launching a nuke on your own. Of course, you can’t be blamed for wanting a little help with the harder, more time-consuming parts, such as the decryption of nuclear launch codes. It’s not an easy mystery to solve and the game makes it a point to keep the details involved nice and shrouded. If you just want to skip this little bit and get to the point where you push a big red button and watch the fireworks, you’ll be pleased to know that there is an app for that – a community-created web app called the Nucacrypt Code Decryptor.

Update: The Nucacrypt website (nucacrypt.com) now displays weekly nuclear launch codes for all three (Site Alpha, Site Bravo, and Site Charlie) silos on its homepage. You needn’t go through the trouble of finding the eight launch code pieces, though you will still need to have a Nuclear Keycard in your inventory. If, for whatever reason, you still find the need to decrypt the weekly nuclear launch codes on your own, continue reading.

What You’ll Need

We’re assuming that if you’re here, you’ve already joined the Enclave, completed the “Back to Basic” and “Officer on Deck” missions to gain access to the Command Center within Whitespring Bunker, gathered all eight code pieces for one of three silos, and have at least one Nuclear Keycard in your inventory. Here’s what you need to do next.

1. Open your PipBoy, switch to the Data tab and note down all eight launch code pieces (for one nuclear silo, of course).

2. Go to the Command Center area inside Whitespring Bunker. On the wall opposite the Command Center’s entrance, you’ll find an “In Progress” keyword displayed for each of the three nuclear silos. Note the incomplete keyword for your silo, complete with empty spaces for missing letters.

How to Get the Decrypted Nuclear Launch Code

1. Go to nucacrypt.com.

2. Hover over Tools and select Code Decryptor.

3. In the text field at the top, enter the incomplete keyworde you noted down earlier, typing question marks or underscores to denote missing letters, as shown in the screenshot below.

4. Enter the letters and numbers from all eight launch code pieces into the corresponding fields below, keeping the sequence the same for both.

5. Click Solve and your decrypted launch code will appear below. Note down the solution. This string of numbers is what you’ll be punching into the keypad in the Control Room.

Note that you may get more than one solution and that each attempt consumes a Nuclear Keycard. If it is manageable, try to match the number of Nuclear Keycards in your inventory with the number of solutions that the app churns out.
