I found this to be more difficult than Heavy Fire Afghanistan but if you play it co op then you'll never die, makes it way easier for sure.
The radios seem to be screwed for me though. I'm playing on ps3 and I did my first playthrough on my one ps3 and got all but 1 radio. Moved my save over and started my second playthrough and got 5/8 radios, bringing my total up to 12/16, and I still haven't received any trophies/achievements related to the radios. I had to move my save over so that I could play with my move because I didn't want to play vet mode with a controller and my setup for my first ps3 doesn't permit using the move.
Gonna go back through the game on easy and get some headshots anyway but I'm a bit disappointed that these trophies may be glitched for me.
The game was released early here in Canada (about 3 weeks-month ago) but I've just been so busy I haven't been able to get around to it yet. I don't think this is supposed to be released outside of NA just so everyone knows. Not 100% sure but from what I've gathered this is a NA exclusive and most Canadian EB Games/Gamestops broke the street date for it.
