I recently gotten splatoon 2 and as a person who never splatoon im having quite some fun!
have you played through the singleplayer campaign? it helps out with practicing your skills with some of the weapon types
in the meantime, does anyone else kind of hate today's salmon run weapons because god, i don't really like any of them except for the carbon roller
especially the tenta brella that weapon loving sucks because it's obnoxiously slow
