Re: Stopping 1 Gold Short (and the Platinum)
As it has been stated a few times already on the game page, all you need on the crushing mode is a litte patience. If you already know where they spawn and where they are coming from it's a lot easier to take them out – aim for the head. It's obviously best to stay out the line of fire for the most the time, in and out, without getting hit. Because it's more like 2 shots and you are dead. Also they enemies will always come to you, so if stay behind a wall waiting for them they will come, so you can take them out one by one as sneak up.
It's actually a lot easier than you would think as long you have your tactis right, obviously there are annoying encounters, like the final battle at the end of chapter 4. I myself completed crushing in 6½hrs, 2hrs faster than I did on hard. All you need is a little patience, and obviously aim ;).
Hope this helped a little,
