Surviving the Aftermath

Pretty simple. Choose a scout as one of your starting specialists to speed things up. While in the colony view, press Y to select the scout at the top of the screen, then press RB to switch panels, and finally press A on "send to world map". Then go to the world map, select the scout, then select an undiscovered area. After a couple days, return to the world map and click on the scout to discover the zone.
