Splatoon 2 test fire day 1 thoughts
Weapons:
Splattershot is the same
Roller is powerful. Long flick gives it versatility and allows for more outplay potential.
Splat Charger is ok. I feel like the range was super short though, but I didn't play much sniper online so I wouldn't know. Holding charge wasn't as helpful as I thought it would be but I'll give it more time.
Dualies are sick. It's like what the splattershot jr. should have been. Short range, good spread, good kill potential, and the power to roll (yes, this weapon is the only one that allows you to roll.)

Sub Weapons:
(Dualies) Curling Bomb is sweet. It's like a seeker you can cook like a grenade. No charge makes it a seeker that bounces off walls. Charge makes it short range like a splat bomb roll to scout corners. I wish you could control detonation though.
(Roller) Suction bomb is the same
(Splattershot) Burst bombs are the same
(Splat Charger) Splat bombs are the same

Special weapons:
(Dualies) Jet Pack was pretty underwhelming tbh. You have no control over your height, you move pretty slowly, and the bursts don't one shot. It's basically an airborne ranged blaster. You can just get killed easily out of the air before you can make use of the special.
(Splattershot) Mortars are pretty cool. I didn't know how to use them at first but if you use them in conjunction with a planned attack it can be deadly. It was most helpful as just an echolocator vision though, and I feel like dodging it was super easy unless you were trapped.
(Roller) Splashdown was pretty cool. Kind of a panic button that totally catches people off guard. One shots everyone in a small radius, but going up and down severely limits your kill potential and I feel like if you're facing any kind of ranged weapon you just end up in the exact same spot you were before and die.
(Splat Charger) Pressure Washer was by far the most interesting to me. Extremely difficult to use correctly, it takes a fairly long time to kill, is hard to aim, but it goes through walls and super long range. I want to play more with this.

Gameplay:
Pretty much the same as splatoon. New button layout is weird to get into but not anything I can't get used to. Pro controller is great for this game. They gyros are build differently and feel different coming from a smaller controller, but it works and I got used to it within the hour.
