When you reach your first home base, you will have a new option to radio the home team and ask for various requests. Tap down on the D-Pad to open the Radio Assistance Menu and pick your option among the choices. These requests cost Influence so take note of that very carefully. The options are very useful especially the Call for Scavengers to sustain your daily supplies. It is highly advisable to send out a scavenger request while you are doing a certain mission. While in a current mission, enter any area like houses, construction sites, taverns, shops, etc. that you haven't searched yet, clear out the zombies then ask for the scavenger to collect the items. This way, you will have a fresh supply of goods everytime.
