These five assignments require you to explore the uncharted worlds of the galaxy and search for items of value. Some of these items can be found from surveying a planet from orbit, while others require you to land on the planet’s surface and physically search for them.
When you land on the surface of a planet, there are usually several areas of interest labeled on your in-game planetary surface map. These areas are almost always directly related to a collection assignment or other UNC assignment.
However, there are often other areas and items of importance that are not labeled on the surface map. The only way to find these is to explore the surface of the planet in the Mako and keep an eye on your radar, which will indicate the locations of these areas and items as you pass near them.
