After the Human-Covenant War, several major corporations in Mindoro, the capital city of Cascade, backed the construction of a new space elevator in the city. The elevator's terminus, Nova Austin Station, was slated to become the most important commercial spaceport on the planet when completed. This construction site was reproduced as a War Games simulation for the UNSC Infinity's SPARTAN-IV complement.
In the post-Covenant War years, conflict also arose on Cascade, which led to the deployment of SPARTAN-IVs to the planet. MJOLNIR GEN2's outer-plate gauntlets were developed for the Spartans fighting on Cascade. The MJOLNIR Powered Assault Armor/Protector GEN2 variant was used in raids on Mindoro and Volamon on Cascade. Additionally, the MJOLNIR (GEN2) ODST armor variant was produced by the Cascade company, Cascade Stronghold Technologies, and tested in Mindoro.
Cascade is known to be home to some agricultural activity. "Technoartisinal" greenleaf lettuce grown on Cascade is used by the restaurant Have S'Moa on Gannick 22 in their "Ground Pounder" burger meal.
