Tomorrow, a new Gamemode will be added to Splatoon roughly at 7PM Pacific Time.
The Gamemode is called Tower Control and is similar to escort the “npc” here types of game. One player will be on the tower and as long as the player stays on, the platform will slowly move towards the enemies’ objective. Friendlies will need to protect their teammate while enemies will attempt to knock them off it. If the platform doesn’t reach either objectives in time, whichever the platform is closest to will lose.
Nintendo Treehouse starts at 29:10.
