These are all of the achievements (Xbox 360) and trophies (PS3) that can be earned from Dead Space. There are 48 in total (8 of them secret) and an additional Platinum Trophy on the PS3 version when all others are awarded. The method for obtaining each one is the same in both versions of the game (excluding the PS3 platinum and big spender because on you need 100K more in PS3 version than in Xbox 360 one).
