Actually, there's one little thing. Normally I never cheat, but I had to during the Armstrong fight. You have to hit him 30 or 40 times and he's got you dead in 3 or so. He's got an unavoidable move. There's a glitch where, according to gamefaqs, he can't hit you when you jump on one of the beds and you can just pummel him, but they don't mention that he just starts chucking grenades at you. I was despairing at the 50th attempt (I've marked them, don't ask), but at the 70th I simply gave up, looked up god mode, activated it, finished the thing, then deactivated god mode again. Further difficult parts (like the timing on that snowy ledge before getting your stuff back) required save scumming, but that's normal. I haven't touched a cheat since, nor will I. I will complete the game, then lie restless, because there was this one bit where I cheated. My success will not be complete.
