There have always been cheaters in Splatoon 2. People doing not-so-nice things behind the scenes to give them a competitive edge in the game. Unfortunately it seems those people are coming out in full force in recent weeks. Reports of users with overpowered weapons are flooding in. There's even users with weapons that have the properties of other weapons, which when combined, makes for almost impossible odds to overcome. Nintendo is yet to address the issue publicly, but hopefully they're working on something behind the scenes.
