In this video guide I will show you how to defeat the Grub Queen in The Maelstrom. So first you will need to clear out three nests to bring out the Grub Queen. The first nest
is located in the middle of the map. You will know you are in the right area when you see the small bugs and what looks like holes in the ground from the eggs.The second location
is located just south from the first location. Basically at the bottom of the map.The final location
is on the east side of the map. You will need to work up north of the map a bit to get into the area. Then follow the path down and into the nest. Once the nest is cleared the Grub Queen will appear. Kill her and get the achievement.
