How to complete Vault integration in Marvel's Avengers

Marvel's Avengers mission chains are quite interesting, however, some of them are quite difficult to get to know well. This is because the game barely explains how you can unlock certain mission chains, and you are on your own if you want to unlock a specific mission chain.

The Vault Onboarding mission chain is one of the few complex missions in the game as it requires a number of stages. You also need to complete the Vault Integration Mission Chain to complete the Reigning Supreme Mission Chain. Here's how to unlock and complete the Vault Integration Mission chain.

Step 1

First, you need to unlock the Vault Onboarding mission chain. To do this, you must first find the SHIELD caches. Inside the SHIELD caches, there are vaults that are marked, and you will get the vault's contact details when you open them. You can check out our guide here on how to find SHIELD caches. Once you have obtained the coordinates of the safe, a mission from the safe will appear on the war table.

Step 2

The second step is to complete a Vault mission. Simply go to the War Table and select a Vault Mission. Complete the objectives to complete this step.

Step 3

The last step is to complete an Elite Vault mission, the Forest Vault. This Vault mission does not require Vault coordinates and should unlock as soon as you complete the first two steps. Once the mission has started, you must continue until the radar appears in the upper left part of the screen. Follow it to reach a place where the distance indicates zero on the radar.

Interact with the white dot on the screen when the radar reads zero and the bunker opens. Once you are inside the bunker, you will see the safe door which you need to unlock. There will be an objective marker that you need to interact with to start the unlocking process. A timer starts and a number appears in the upper left of the screen. Go to the terminal with the number highlighted to activate it. Once that is done, the second number will be highlighted and you have to stand on the respective terminal and wait for Jarvis to activate it.

Once you've activated both numbers, return to the safe. Stand in the square in front of the safe and beat all enemies until the blue bar in the top left is filled. Once this is done, you have to repeat the whole process two more times, each time with an additional terminal. Repeat the process three times will open the door to the safe. Enter and collect all the loot. When you're done, interact with the green terminal to complete the mission.

Once you have completed all three stages, you will have successfully completed the Vault Mission Chain. This will also complete one of the Days Ahead mission objectives that you need to complete for the Reigning Supreme mission chain.
