A brand new mode is going to be made available for Splatoon players everywhere on July 1 at 7PM PST. It’s going to be a “tower defense” mode, with a twist, in that you are actually defending a tower.
“Once someone jumps onto the tower, it starts moving along a set path toward the other team’s goal,” Nintendo explains. “If the tower doesn’t arrive at their goal before time runs out, the team that’s moved it closes toward their opponent’s goal wins.”
“Ride the tower all the way into the other team’s goal though, and you’ll get a decisive knockout victory.”
