Nintendo has used their Splatoon Tumblr page to showcase two new weapons. Both will be included in a set of eight weapons that will arrive tomorrow, along with Splatoon’s 2.7.0 update. Feel free to check out the information on both weapons below.
Soda Slosher
The Soda Slosher is based on a regular ol’ Slosher, but with some adjustments to the setup. Splat Bombs support the basic strategy, and the addition of the Inkzooka provides ranged power lacking in other models. And the bucket colors are pretty sweet too. Just sayin’.
Bamboozler 14 Mk III
According to Sheldon, this set REDEFINES what it means to be a Bamboozler! Do you think you’re ready? The Bamboozler 14 Mk III takes the Mk I and swaps out the barrel for a different bamboo pipe. This set’s selling point is how the main weapon and the Burst Bombs can really hammer your opponent! That’s not to mention the Inkstrike, which can make life difficult for even far-off enemies.
Thanks, MasterPikachu6

So…not “new” just tweaked…
Ok.
I hope the success of this game hasn’t taught Nintendo any bad lessons.
