An anonymous streamer has gotten his hands on a copy of Mario Tennis Aces two weeks before its official release date.

The streamer has started streaming gameplay of Mario Tennis Aces’ Story Mode, so you may want to stay off Youtube to avoid seeing spoilers. It’s unclear how the streamer got a copy of the game this early, but someone spotted the game selling out quickly on Craiglist, so a retail or distribution employee may have smuggled it out.

If you don’t mind spoilers, there’s currently a livestream going on here.

Mario Tennis Aces launches June 22, 2018 on Nintendo Switch.
