Azure Striker Gunvolt 2 is a sequel to the side-scroller of the same name, in which the main antagonist from the previous game named Copen becomes available as a playable character. Players control a hero called Gunvolt. He fights with high voltage and insanely fast speed. His ability is called seventh.
The new character Kopen has a number of individual moves and characteristics. He is able to shoot down enemies at full speed and take aim at opponents, releasing a series of homing missiles. One of the main features of the gameplay for the anti-hero is that he can copy the abilities of defeated bosses.
After completing the main game mode, an additional Story Mode + is unlocked, which better reveals the interaction between the characters and includes more than 20 songs of the virtual K-pop group "Muse". This mode features an adventure from the perspective of the villain of the franchise. The passage for Copen contains one level less than the main Gunvolt, but at the same time shows a completely different ending. Many cutscenes in Azure Striker Gunvolt 2 are intertwined, as the characters will often interact with each other during the passage.
