Middle-earth: Shadow of Mordor - Game of the Year Edition

Rattle the Hive - 30G

As per REJECt444's solution for the standard edition of the game, you unlock the ability to bait ghul mounds in the Lord of the Hunt storyline, during the Matron's Rising mission. You will have to bait at least 3 mounds as part of that story mission, by shooting the mounds with your bow. You'll also get another chance to rack up 10 during a later story mission when you're learning to brand ghuls, but if you don't get it then, or, like me, want to grind it out quickly here's what I did:

Guide
Fast travel to the Forge Tower at Cab-Gwanath Bluff, it's the one on the top-right of the map. It doesn't matter if it's the day or at night, so you won't need to advance time.

Stay on the Forge Tower and walk forward and to your left, and draw your bow (). You should see the telltale green of the mound on the ground on the side of the road nearest to you. Shoot it with

Extra steps from Warboy925:
Turn around, head to the opposite edge of the tower, you will see another mound just to the left of a tree.

Turn right and head to to edge of the tower, you will see ANOTHER mound on the lower left side!


Now, fast travel to the Forge Tower again. Rinse and repeat until the achievement pops, shouldn't take more than a couple of minutes.

Hope this helps, any suggestions/feedback, let me know and I'll update!

Edit: Updated to include Warboy925's great extra steps, which make the whole thing over 3 times faster (fewer loading screens are always a good thing).
