I love this game so much. I have over 200 hours on it, and I feel terrible that I'm on vacation and can't play it right now Splatoon is like a drug for me, heh.
Considering there are still maps and weapons to unleash, I'm really wondering when we'll start seeing those. The updates were pretty regular before the major one.
It's a squad with two people. It's essentially the same thing as regular quad squads except it pairs two twins against two twins. So, it'd be like me and my friend + someone and their friend Vs. someone and their friend + someone and their friend.
