How to reach Mars in Black Ops 7 Zombies Astra Malorum – Main easter egg guide

Visiting the Red Planet, a.k.a. Mars, is quite crucial in Black Ops 7 Zombies‘ Astra Malorum map if you’re looking to complete the main easter egg.

Things would have been easier if we could have got ourselves a spaceship to travel to the location. Unfortunately, such a facility isn’t available inside the game. Instead, we will have to open a teleportation portal to reach Mars. This guide will briefly state all the vital steps you need to complete to reach Mars.

How to access Mars in Black Ops 7 Zombies Astra Malorum

The first prerequisite is to unlock the LGM-1 Wonder Weapon. We already have a detailed guide that will help you get this Wonder Weapon. You’ll first have to find a few items, followed by eliminating O.S.C.A.R. with traps at three different locations.

Once you have obtained the LGM-1, wait for O.S.C.A.R. to spawn once again. Once he spawns, he will direct you to a location. Just stay away from the spotlight in front of him, and you won’t have to take a hit. You can try damaging him from the back, but it’s not necessary. Continue this trail until you hear a recording of Thurston speaking the names of three planets. Note the names of the planets and their order.

For example, the order of planets on my playthrough was Mercury, Venus, and Neptune. To get the code, apply the numeric position of the planets as per their distance from the Sun. In the example above, the code will be 128. Noting the order is crucial if you want to crack the code successfully.

Once you receive the code, reach the Observatory Dome room. You’ll find a small terminal near the Pack-A-Punch. Enter the code, and it will activate a lift. The lift will come down (in front of the Pack-A-Punch), and you’ll find a corpse. Take the key from the corpse, and proceed to Museum Infinitum.

You’ll find a saw in a glass display. Break the glass to obtain the saw, and head to the south room of Machina Astralis. Here, you’ll find a body in the Cryopod. Stand close to the head, and interact with it to grab the brain (must have the saw for this part).

Head to the Luminarium, and you’ll find a brain kept on a table. Replace it with Thurnston’s brain, and defend the location for 60 seconds. Once done, pick the brain up and head to Machina Astralis. You’ll notice a strange set of machines on the ground floor (right in the middle of the building).

Place the brain in the machine next to the teleported pad, and it will turn on automatically. The machine will display the Thurston’s Reading List, and a set of books will appear. Note down all the books (the names will be random, so be careful about this step).

Go back to the Observatory room and interact with the telescope as you did to obtain the LGM-1. Instead of looking for the Sun, look for Mars. Check the bottom left to find your coordinates. Enter the coordinates on a terminal located in the eastern part of Machina. If you enter the correct values, Thurnston will mention that the coordinates are for Mars.

The next task is to go to the Archive and look for three statues. Each statue has a set of bookshelves. Your task is to check the books in the shelves and interact with the bust. For example, I had The Musica Universalis among my list of books. None of the other shelves in this lot had books that appeared for me. Hence, I interacted with the bust only once. In simple words, interact with a specific bust as many times as you find the correct book in the shelves (Interact twice if there were two books, and so on).

You can interact with the busts only when a new round begins. Hence, you’ll have to be quick (or wait for a new round). You can complete interacting with the three busts across multiple rounds. Once this part is done, take the ladder in the corner of the Archive and climb up. Take the Neptune model and place it at the giant planetarium at the top of the Machina.

You’ll also find three notes in the map (I believe their locations are fixed, but the planet and directions differ).

• Check the big circular room’s second floor for the first piece of paper.
• You’ll find one in the trap room of the Luminarium.
• The final one can be found in the Archive room itself, lying on top of a table.

Note down the directions and planets mentioned on the papers. Head back to the top of the planetarium, and shoot only these three planets till they’re aligned in their correct positions. You can figure out the positions from the underside of the giant Sun.

Go to the strange machine on the ground floor of Machina and press F. If the three planets are aligned correctly, it will activate the portal. However, the portal will take time to charge up fully, and an O.S.C.A.R. and other zombies will attack you. Your objective is to take down the flying discs of O.S.C.A.R., since those can reset the progress of the portal.

Wait for the portal to finish its activation, and you’ll be teleported to Mars, where you begin the last phase of completing the main easter egg of Astral Malorum. Reaching Mars is also necessary if you’re looking to complete the main musical easter egg and unlock a track from Avenged Sevenfold.
