"The existence of a brand-new sub weapon, the Fizzy Bomb, was just confirmed in the latest Ver.4 trailer! We heard that once you activate it you can shake it like a can of pop (or soda depending on your geography) to generate power once it's released! This carbonated sub weapon will be included in weapon sets arriving in early October."
