Tutorial tune I think is in testing weapons, normal battle tune was the beta Splattack, in which is really good, last minute did make it due to its lack of high energy
I used to think the E3 trailer of this game was weird as hell- but eventually it caught my attention to the point where I really love the idols- the Squid Sisters in particular. Splatoon1 became my first shooter game, and led to me playing 2, and 3.
It would be cool to see the Splatoon character as a DLC challenger for Smash Bros being avaliabe on launch day of the game to celebrate (that's if Nintendo do this).
