Ok so I have the game on medium, and I just got done with the whole marijuana plantation part, and that was the first island I went to. And that took melike 3-4 tries.
And now I keep getting owned hard when I try to get to the next spot on the radar. Health/armor packs are rare, and the only ammo comes from guys you shoot.
It's awesome, much better than it appeared to be from the first part of the game. And the AI is a lot better.
