Vestige is a 1 bomb assault BTB map base on a dormant Forerunner installation. Using massive Forerunner structures as the main base the defenders must prevent blue team from planting the bomb in the core room. Vestige also has the addition of a small secondary objective for both teams to fight for the control over the cartographer building where they will find a control switch that toggles a light bridge on the opposite side of the map. This light bridge give the attacking team a third lane of advancing on the main base, which for the defender means more lines of sight they will need to cover.
