Great guide, Nozza.
Thought you may want to know for the "Love the Boom" Achievement - Kill 4 enemies simultaneously with one explosion. I found an easier way to do it.
The Trial of the Rakyat located at 756.5, 746.0
It's a trial where you have to get kills with an RPG. There are a couple times where I got multiple kills with one rocket. That's where I unlocked the achievement. For those who are fighting the other way.
Your dog may know how to sit and stay, but mine steals bank accounts. She's the true Watch Dog!
Thanks Rajeanero for the awesome work.
