Rocket Launch Puzzle Solutions in BO7 Zombies

Progressing through the Ashes of the Damned main easter egg in Call of Duty: Black Ops 7 Zombies is no easy feat, especially when you reach the infamous rocket launch step in the Zarya Cosmodrome. This part of the quest introduces a randomized symbol puzzle that can easily derail a run if you don't know exactly what to look for. Between endless zombie spawns, time pressure, and cryptic symbols, many players fail this step simply due to confusion.

Thankfully, the rocket launch puzzle follows a fixed logic once you understand it. By translating the symbols correctly and inputting the right numbers, you can launch the rocket smoothly and continue progressing toward the final upgrades for Ol' Tessie and the completion of the Ashes of the Damned easter egg. This guide breaks everything down step by step so you can solve the puzzle quickly and get back to slaying the undead.

How to Prep the Rocket for Launch in Ashes of the Damned

Before you can even attempt the rocket puzzle, you'll need to complete several prerequisite easter egg steps. First, you must acquire the Necrofluid Gauntlet, followed by gathering Serum ingredients and solving the Serum puzzle. After that, you'll need to locate and deliver all three keys found along the roads leading out of Ashwood.

Once those steps are complete, you can obtain the DG-2 Turret Barrel upgrade for Ol' Tessie. Install this upgrade and use it to shoot the floating clock tower in Ashwood. When activated, the tower will glow. Immediately shoot it with the Necrofluid Gauntlet, and reload-if done correctly, the weapon becomes spectral and glows purple, indicating it's charged.

With the gauntlet charged, head to the Zarya Cosmodrome, either by driving Ol' Tessie southeast from Ashwood or by using the Jump Pad near Double Tap Root Beer for a faster route. In the Cosmodrome, look northwest and northeast to find two rapidly spinning array towers. Shoot one tower with the charged Necrofluid Gauntlet to slow it down. Then return to Ashwood, recharge at the clock tower, and repeat the process for the second array.

Only after both array towers are slowed can you move on to the rocket launch puzzle itself.

Understanding the Rocket Launch Puzzle

Once both arrays are dealt with, enter the Control Room in Zarya Cosmodrome, near the Wisp Tea machine. On the north wall, you'll see two screens flashing six unique symbols. These symbols always spell one of four possible words, but the symbols themselves change each game, which is why this step feels random.

The symbols are translated using a Pigpen cipher, and once translated into letters, each letter must be converted into a number. The alphabet starts at A = 00 and ends at Z = 25. While this sounds complicated, the puzzle always resolves to one of the following four words.

All Rocket Puzzle Solutions Explained

Below are all possible symbol combinations, their translated words, and the exact numbers you need to input:

·ROCKET

Symbols: FE-LU-□>

Numbers: 17-14-02-10-10-04-19

·LAUNCH

Symbols: LJ-□-LN

Numbers: 11-00-20-13-02-07

·WEAPON

Symbols: Y□-J|-CO

Numbers: 22-04-00-15-14-14

·ENGINE

Symbols: □□-''||''-□□

Numbers: 04-13-06-08-13-04

Once you identify which word your symbols represent, turn around in the Control Room and locate the six computer terminals on the northwest side. Each terminal cycles through numbers rapidly. You must shoot the red button on each terminal to stop the number at the correct value, entering the sequence from left to right.

For example, if your symbols translate to ROCKET, your first terminal must be stopped at 17, the second at 14, the third at 02, and so on, until the full sequence is entered correctly.

What Happens If You Fail?

If you input the wrong numbers, the launch sequence will fail, and you'll have to wait until the next round to retry. Unfortunately, this also means repeating the array tower charging step, which can be dangerous due to constant zombie pressure. This is why knowing the correct translations ahead of time is critical.

Practicing this step in a low-pressure environment, such as Call of Duty Black Ops 7 Bot Lobbies, can help players memorize the process and avoid costly mistakes during real runs. Some players even choose to buy CoD Black Ops 7 Bot Lobbies specifically to rehearse complex easter egg mechanics like this without risking failed attempts.

Successful Rocket Launch Outcome

When the correct sequence is entered, the puzzle resolves immediately. Zombies despawn, alarms cease, and the rocket launches dramatically into the sky, signaling successful completion of this step. From here, you can continue the Ashes of the Damned main quest without further puzzle-related interruptions.

Final Tips for Consistency

The rocket launch puzzle may seem overwhelming at first, but it's entirely deterministic once you understand the symbol-to-word translations and number conversions. Save this guide, memorize the four possible solutions, and the step becomes one of the easiest in the entire easter egg.

With proper preparation, clear communication, and quick execution, you'll have the rocket airborne every run and one step closer to mastering Black Ops 7 Zombies.
