"Tomorrow, on 7/1 at 7 PM PT, a new Ranked Battle will be added to the game! This new mode is called Tower Control. Hop aboard the tower placed in the middle of the map, and ride it to your opponent’s goal. stay sharp—you’ll have to protect whoever’s riding the tower from enemy attacks!
Once someone jumps onto the tower, it starts moving along a set path toward the other team’s goal. If the tower doesn’t arrive at either goal before time runs out, the team that’s moved it closest 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."
