As all of you know, there are four types of resources available in "Domination: Earth": Money, Supplies, Personnel and Unobtainium.
All resources, except for Unobtainium, appear in random locations within a 5 kilometer radius around you after every check-in (i.e. Capture Land).
Resource locations are shared between players, which means that any resource that you can see on the map is visible to all other players nearby as well, so you have to get the resource before someone else does.
