Secrets Within Tips and Strategy

How to Find the Vault

Make sure to keep an eye on the radar tracker on the left side of the screen. The closer you get to the vault, the smaller the number becomes. Once you're below 10m close, you can use your Tactical Awareness to find the switch to open the vault.

Bring Support Heroes

This type of mission tends to last long, especially after you unlock the Vault. With such a long series of battles ahead, Ms. Marvel's Healing Spirit, which will ensure the survivability of your strike team, will be invaluable.

Have Area Damaging Moves

The tendency in this mission as you unlock the Vault is for enemies to swarm you. Having area damaging moves will help clear out huge waves of enemies quickly.

Dodge and Wait As An Alternate Strategy

If you're finding the vault enemies very difficult, then, mastering how to perfectly evade your enemies will be crucial. You actually don't need to defeat all of the enemies. You just need to survive long enough for the vault to blast its EMP to defeat all enemies in an instant.

Solving The Puzzle: Western AIM Building

This building contains the agent you need to rescue. Here are the locations of the switches.

Floor Switches

Locations
	The first two are in front of the building.
	Go to the side of the building to find an exhaust fan. Destroy it and enter the building to find the next switches.
