Time to pull out this thread again, because Nintendo has just announced that the Carbon Roller Deco will be coming out tonight, complete with the only new Special Weapon we will ever get, Seeker Rush itself! It's time to actually get to use and analyze this thing in multiplayer, and see how it works!
Also, if you want to practice with this thing beforehand, remember, this can actually be used in the game currently, but only in single player. Go to any level with a Bomb Rush powerup and switch to Seekers, and then you can test it out from there. I recommend Level 20, Octoling Uprising: Battle at Bluefin Depot, which is as close to multiplayer as one can get and it has a Bomb Rush powerup right before the area where the zone is.
