Cold War Decoder

A command-line tool to solve the "Operation Chaos" puzzle from Call of Duty: Black Ops Cold War.

Evidence Needed

To use this tool, you need to have found the three pieces of evidence from the campaign missions:

1. A Coded Message (from mission "Brick in the Wall"): This provides two number sequences (one red, one blue) with a missing number in each.
2. Numbers Station Broadcast (from mission "Echoes of a Cold War"): This provides a list of cities and their corresponding number station codes.
3. Front Page of the Observer (from mission "Nowhere Left to Run"): This newspaper contains a scrambled word (a city name) highlighted in red.

Usage

You need to run the application providing the information from the evidence as command-line arguments.

Arguments

• --stations or -s: The list of cities and codes from the Numbers Station Broadcast.
  • Format: CityName1=Code1,CityName2=Code2,...
  • Example: Atlanta=1234,Boston=5678
• --scramble or -c: The scrambled letters from the front page of the Observer newspaper.
  • Format: A string of letters, can include spaces.
  • Example: "NEWYROK"
• --red or -r: The red number sequence from the Coded Message. Use ? for the missing number.
  • Format: A comma-separated list of numbers.
  • Example: 1,2,?,4,5
• --blue or -b: The blue number sequence from the Coded Message. Use ? for the missing number.
  • Format: A comma-separated list of numbers.
  • Example: 10,20,30,?,50

Example Command

With gradle:

./gradlew :app:run --args="--stations 'Houston=6195,Atlanta=6287,Tucson=6373,Miami=6459,Dallas=6625' --scramble 'SNOTOB' --red '22,23,?,27,29' --blue '53,?,57,59,61'"

After building a JAR (./gradlew :app:jar):

java -jar app/build/libs/app.jar --stations "Houston=6195,Atlanta=6287,Tucson=6373,Miami=6459,Dallas=6625" --scramble "SNOTOB" --red "22,23,?,27,29" --blue "53,?,57,59,61"

Output

The tool will output:

1. The unscrambled city and its code, which is the first passphrase.
2. The missing red and blue numbers.
3. The combined code from the missing numbers and the corresponding city, which is the second passphrase.
