Even more Splatoon 2 weapon kits have been revealed, aaaaaaand the Slosher lost it's Burst Bombs...
As for other interesting tidbits, Sprinklers, Splash Walls, and Squid Beacons have been confirmed, thus every sub weapon from the original returns in some form or another. As I thought, the Scoped variety of Chargers do not have the ability to hold their charge while swimming, only the non-scoped can. Dynamos can indeed vertical flick, but how good or not it is has yet to be seen. Lastly, there's more specials that haven't been revealed yet.
