The Vektan Slums are pretty self explanatory. Rico lived his life here as a young boy helping his mother. An entire mission takes place here where you're looking for Gregor Hakha. Plenty of posters are seen all around the slums where planets companies and resorts are seen displaying. The slums even has its own mall where Pvt Sanchez dies. The multipayer version of this map is nearly exactly like the campaign area.
