It's weird because I've played with so many foreign players, it's like they're getting their own private party.
I played a lot of normal and ranked Saltspray Rig/Port Mackerel/Arowana Mall/Urchin Underpass last night, and while my strategy for Arowana and Urchin Underpass are pretty much locked down, my Port Mackerel and Saltspray Rig game leaves something to be desired. I do find the Modified Blaster extremely effective because of its range and explosive nature that allow for taking out perches, and though the Proximity mines are amazing for Splat Zones they are best suited for that mode alone. Still struggling to find a good weapon for normal turf wars, I've been switching a lot between Splatershot Pro and N-Zap which has insane damage output.
52. Gal Deco with sprinklers and echo is probably one of the best weapons for Arowana, IMO. And while I didn't do very well on Port Mackerel, I'll admit it is one of the most fun Splat Zone stages because of it's two capture points.
EDIT: Cat scum need to check themselves. Team Dog Strong, Brave, and more cunning than you think.
