Question: Do ink mines have some kind of power that automatically places a mine because EVERY SINGLE PERSON who has it as a sub ALWAYS leaves a mine when they get splatted.
Anyway I just found an amazing strategy for splat zones on Saltspray Rig. Once your team has secured the area, swim to the top of the walls so that you're on the top and have a good view of the enemy's base. From there, hid in ink until you see your enemy coming. Then, jump down and destroy them then swim back up and repeat.
