EX Downtown (EXビル街) is a Score Attack exclusive mission in Azure Striker Gunvolt 2. It was originally released for the 3DS version as part of the fourth DLC pack Ultimate Challenge alongside EX Frozen City, and has since been included in the console Striker Packs and Steam release by default. It is a heavily altered version of Downtown from the main game modified to be much harder, with Zonda's false forms as the boss, also with heavily modified attacks.
While completing the stage as Copen is challenging, certain platforming segments make completing it as Gunvolt very difficult due to his comparative lack of mobility. Gunvolt's version of the stage has Sumeragi soldiers, while Copen's version of the stage has Blood Servants.
