How to unlock the Call in the Cavalry achievement in Crackdown 3: Campaign - Definitive Guide
If you go to any Supply Point, open up the Loadout menu, and then go into the Gadget menu, you should just be able to select the Peacekeeper Beacon from the bottom row on the left. After exiting the menu, you can activate the beacon by hitting the button on your controller.
The game seems a little picky about where you can deploy the beacon as i kept getting the message 'Cannot perform action' every time i tried to deploy it right next to the Supply Point. Just keep moving about and spamming the beacon, at some point it will activate for you. What worked for me was to go somewhere on ground level, near water/the shore and try deploying it there.
The Peacekeeper Beacon gadget is available at supply points once you have liberated all 12 Prisoner Hardpoints throughout the city (refer to "Liberator" for more information). Once you've done that, the gadget will be available. If you've already done this as of receiving this update, the gadget will be automatically available to you.
To equip the Peacekeeper Beacon, go to any supply point and select it as your gadget (first gadget in the bottom row). To use the beacon, you must be in an area of the city where peacekeepers can respond to your call, so if you are on top of a building, under a bridge, traveling on pipes, etc., it cannot be used. Once you are in a suitable location, press to throw the beacon and the achievement will unlock.
