EX Frozen City (EX凍結都市) 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 Downtown, and has since been included in the console Striker Packs and Steam release by default. It is a shorter, heavily altered version of Frozen City from the main game modified to be much harder, with Copen or Gunvolt as the boss. Copen's attacks are far more aggressive, while Gunvolt's move set completely changes in the third phase of his fight.
Completing this stage as Gunvolt will reward the player with the Dyaus Clip, while completing it as Copen will reward the player with the Infinity Drive.
