Dead Space can be done in 2 1/2 play throughs. The plasma cutter fully upgraded is actually the best weapon in the game IMO. Its fast and powerful and ammo is the most abundant and cheap to buy. I did normal 1 1/2 times to get all weapons max and I did Impossible with the plasma cutter only. By the time your ready for Impossible difficulty you will know how to kill all the enemies and solve the puzzles right away so it'll be much easier and a lot less scary. Good luck
