For every weapon in Splatoon, there is a variation with a different look, sub weapon and special weapon. Those that do not have it yet will most likely get it in the future. Case in point: the Carbon Roller Deco, which releases tonight in North America and tomorrow in Europe. As sub weapon it has the Seeker and as special weapon it has a Seeker Bomb Rush.
Take a look at the gallery below if you want to see screenshots of this weapon in action!
