I love the game, but I have found a bug that make it very frustrating. I can't seem to get the achievement for beating it in hardcore mode. The first time I made it to the helicopter, the game brought me back to what would have been the checkpoint (though there are not supposed to be check points in the mode) before the cut scene after I tried to skip it. Since then, I have beaten it a second time, without that happening, but I still don't get the achievement. This is very frustrating because it take at least 4 hours to beat hardcore mode and I have does so twice with nothing to show for it.
