Mass Effect’s uncharted side assignments often require players to search the galaxy in order to find specific pieces of a collection.

UNC: Valuable Minerals is one such example. This assignment is unique due to its four distinct categories of items players need to find. These can be located either by landing on the surface of a planet and uncovering deposits through exploration or by surveying individual planets from above their atmosphere. Of the four categories, players need to collect 20 individual pieces of heavy metal, light metal, and rare earth with six deposits of gas.
