There are a lot of items and abilities you will need to unlock in Agents of Mayhem, but one of the most critical are Agency Upgrades. These can be found at the Requisition desk in The Ark, which will unlock quite early into your playthrough. From the spawn, turn left and head over to the desk with the large sign that reads “Requisitions and click Triangle (PS4)/Y (Xbox One). You will need to be at least level 6 to unlock the Upgrade Agency section, but once you have this just click on the middle tab to bring it up.
Players will then see a list of perks, each with a predetermined cost and level that you will need to reach in order to obtain them. All you have to do then is scroll down to the upgrade you want and press X (PS4)/A (Xbox One) to purchase that specific passive. While it can be easy to ignore these perks, make sure to grab at least some of them during your playthrough. Agency Upgrades are quite expensive so you’ll want to be careful with which ones you buy, as many of them only offer little rewards for the high cost needed. There is no limit to how many upgrades you can have unlocked at any time, so if you have the cash buy as amny as possible.
In order to unlock every Agency Upgrades, you will need to be at level 18 which can take a bit of time. If you really want to get a lot of experience make sure to unlock the “GonePro” Combat Diary Camera passive and then do a bunch of side activities out in Seoul. This will help you rank your Agency Level up quickly and allow you access to all of the Agency Upgrades early on into Agents of Mayhem.
