Iron Sea Defenders – Quartermaster Achievement Guide

Here’s a sure and easy way to get the Quartermaster, the requirements are level 16 on Atlantic Ocean (I’ve done this in easy mode).

How to Obtain Quartermaster Achievement

What you’ll need to do is put an oil rig at the bottom right of the map and make it a tesla tower.

This tower has the power to return a ship to the beginning point of it’s route and as this tower is the only thing that’ll damage the ship your other oil rigs will have a lot of time to generate money.

I personally did this at the 5. wave with a single ship but if you want to you can start earlier.
