Vouchers
Consider exploring levels as you can get vouchers for Krusty Sean’s stand in Inkopolis Square (screenshot above), where you can gain bonuses for Splatoon 2’s online matches.
New Weapons
Make sure you try out new weapons once you have unlocked them as each weapon is suited to a different type of combat, from the close range Splat Dualies to the long range Splat Charger.
Easy way to get Ability Chunks
A decent method of getting Ability Chunks is by scrubbing low-level gear that you can get at low prices and then investing those Ability Chunks in better clothing.
Learn the Map
Learning the shortcuts that can be found littered thoughout the maps in Salmon Run can make or break a run. This becomes obvious in harder difficulties where seconds can mean the difference between having enough Power Eggs or coming short.
Fog
In Salmon Run your viewing distance will be dramatically obscured by fog so make sure you compensate for this by making use of your beacons to ensure players know where the Salmonid are, and also where teammates are.
