Hero mode only, I don't play multiplayer games these days, and even if I did I wouldn't touch Splatoon's multiplayer due to it's map rotation system. I'd enjoy this more if they didn't insist on forcing you to use awful weapons for half the levels. I assume the reason they force you to use certain weapons for certain levels is that they want the campaign to be somewhat of a turorial for the multiplayer, but I wish they'd just let hero mode be it's own thing. I also really don't like the hub areas. I usually love hub worlds, but in this they're annoying to navigate to find the levels and you end up spending more time doing that than playing the actual levels. There's a great game in here, they just need to stop nintendo-ing it up and insisting I play it the exact way they want me to (forced bad weapons) I will say the last boss was less frustrating than in the first game, primarily because it was just a boss, whereas in the first game the boss was part of a level where you had to go through each section before fighting each boss stage (I think, it's been a while since I played it)
