Unbound Glory

For this achievement you have to be the FIRST to open the crate. You have to open the crate to reveal the chest to get credit. Looting the chest after the crate is opened by someone else does not count.

I found an easy way to do this. I did it in Isle of Dorn because I was already there. The plane that drops the Supply crate spawns far South East of the map. I would stand near 61,58 and wait for the chest. it spawns every 18 minutes. When the plane pops up fly with the plane until you figure out which coordinates it will land. Go to those coordinates and start spam clicking. There are 2 drop coordinates where the plane drops the box quick because it is right next to where the plane spawns.

Here are the drop coordinates: (I will add more to this post later)

It doesn't look like opening War Supply chests in Undermine counts toward this achievement.

Doesn't count in Karesh for some reason
