Distress beacons for cornered players?

Also, not sure if you have this idea already, but the npc survivors could be turned zombie, either when an outpost is taken or npc survivors are trapped in various areas and need to be saved and escorted to a outpost before zombie npcs find them.

also also, An objective of the players could be to restore utilities to certian areas. I.e electricity to provide an outpost with power for lights or turrets. Water to keep survivors alive. Power for city street lights at night etc. Utilities would then have to be defended to maintain power or whatever.
