I was thinking of adding care packages. Not like what you might see in CoD, but with a certain amount of supplies (randomly generated?), including food, gear, some ammo, and maybe a pistol or two. They would drop from the sky in a random place (out of a plane going across the sky if possible, so people could know the general direction it dropped). One could be spawned every half hour, with a maximum of 5 or so in the map at any time, and each would disappear after being on the map for 1-2 hours. Of course those numbers are subject to change, I'm sure.
