I Have found great success with the Aerospray MG, its not quite as combat efficient as the N-Zap but it is far better for coverage, its ultimate I find so far more useful than the drink cabinet too.
You can still make it work by getting up close, its poor accuracy but high RoF means at close range you will naturally burn people down faster than the more accurate ones, shame its grenade type sucks but again great coverage if cooked to stage 3, but it is what it is, people still move out the way when you toss one.
Just managed to order in a stealth hoodie from the Nintendo app means that I will be invisible in inkling form (no splashes) I would advise anyone who hasent to download the Nintendo app for mobile load up splatoon and get a order up for it asap, got anouther 12 hours, and it's nice to have essentially anouther shop with unique gear to shop from.
Once ordered just get enough cash and head over to Murch
Normally apps for games suck, but for splatoon 3 it feels almost mandatory, they have a QR code scanner for unique rewards and also a kind of event where you earn currency with the turf you splat in turfwar to unlock some unique items too, overall I would recommend using it.
