Underground Weapon is Dangerous in Splatoon

The latest Splatoon account tweet is a piece of artwork from one of the locations in the game.

The translation reads "We received a sketch from one of our researchers," and how the artwork depicts a "giant weapon" that was created by the antagonists of the solo campaign, Octopus Army Corps. Players will need to save the poor Battery Catfish from the weapon, as they're being used as a power source, taking "down the weapon while withstanding its powerful attacks."

How do you think the solo campaign is shaping up in Splatoon so far?
