Hey guys, I was wondering if someone here could give me a little help with Dead Space. I have just completed my first run through on medium and unlocked all the stuff that comes with it (10 power nodes, military suit, etc) and I have also done the entire thing to get the 'One Gun' achievement, and I ended up finishing the game with every single node upgraded on everything I have, so that's the suit, the plasma cutter, the kinesis and stasis. However, I would like to be able to use this save file to beat the impossible difficulty, but I do not know how to change the difficulty of a save file. Is there any possible way of doing this?
This is probably the wrong place to post this, but I have a question that I didn't want to start a new thread about: After you complete the game, do you unlock a level select screen? Because I did it the old fashioned way and have a save file at the beginning of every level I have completed so far.
