I've found myself incredible frustrated with Hard mode. The achievement whore in me is probably taking the fun away from the game for me instead of playing on Normal where it isn't as brutal. Finding some checkpoints are placed a little too far a head. Just completed the Panama mission and I'm hoping I can complete the game without bumping down the difficulty. Max is so damn fragile and the enemies almost always get headshots. It really changes the game and almost makes it tactical. If the game didn't take pity on me for dying so many times by giving me a bottle of pills when I reload, I don't think I could do it.
Anyone else playing on Hard mode?
