Unbelievably frustrating
The environment is largely the same, with lush jungles and some hut villages that allow your view to be obscured, but allow snipers 1/2 mile away to see you and pick you off while you have a leaf in your face obstructing your view.
At least you can reload and be more careful at that same spot, right?
Wrong.
There are pre-determined save spots that seem miles apart, ensuring that you play the same frustrating showdown half a dozen times before you get lucky enough to get it right.
There are few games I actually stopped playing prior to their finish due to frustration and repetitiveness. This is one of them.
