Other than that, you guys did a fantastic job especially with the environments in Bolivia, the weapons sound amazing, movement and body animations is great as well. The not so good, Bowman sometimes annoys me with her dialogue, and for drop-off vehicles, 7 times out of 10, they spawn in the strangest spots.
The music isn't that iconic I agree, except the GRW menu theme (https://www.youtube.com/watch?v=9Ad8WKG4BRw) I adore that one.
