Spoiler alert! The list contains storyline revealing secret Achievements!
Dead Space Achievements are very similar to PS3 Trophies- and they're the same awesome. One or two of them are a bit more difficult to achieve if you would decide going for maximum. In any case, don't expect to collect all of them in a single play-through. For instance Maxed Out (upgrade all weapons and equipment) or Epic Tier 3 Engineer (complete the game on the hardest difficulty setting) require some further dedication. Good news that the game is awesome and you'll want to play it more than once!
