Dead Space 2 Achievement Guide – Game Completion
Made Us Whole (10 GS/Bronze)– Complete the game on any difficulty setting.
- Mission Impossible (50 GS/Gold) – Complete the game on Zealot setting. Though you can choose to embark on a Zealot run for your first playthrough, it is highly advisable that you complete the game on the Normal setting first. After completing the game on Normal you can start a New Game+ on Zealot difficulty, carrying over all your weapons, Power Nodes, money, and recovery items. This will make a Zealot run much easier. Note: "Mission Impossible" does not stack with the "Hard to the Core" achievement; a minimum of two playthroughs are required to unlock both.
- Hard to the Core (50 GS/Gold) – Complete the game on Hard Core setting. To unlock Hard Core difficulty, you must first complete Dead Space 2 on any other difficulty setting. This mode is unique in that you cannot begin a New Game+ run on Hard Core, forcing you to start from scratch. You'll also only get three opportunities to save your progress. This is arguably the hardest achievement in the game, but earning it unlocks a powerful new weapon: the Hand Cannon.
Dead Space 2 Achievement Guide – Collectables
Romper Stomper (25 GS/Bronze)– Stomp 10 containers. Containers stuffed with ammunition and money are found throughout The Sprawl. They are identified by their green color and glowing white corners.
- The Engineer (10 GS/Silver) – Collect 10 schematics. Schematics are used to unlock new weapons/upgrades at the shop, and are usually found behind locked Power Node doors. Try to keep at least one spare Power Node on hand at all times to ensure you don't miss any. There are more than 10 schematics in Dead Space 2 so you don't need to collect them all for this achievement.
- The Electrician (10 GS/Silver) – Collect 10 semiconductors. Semiconductors are typically found in supply caches after defeating tougher enemies like Brutes or Tripods. There are more than 10 semiconductors in the game, but they can be sold for heaps of cash so it's wise to seek as many out as you can.
- The Librarian (10 GS/Bronze) – Collect 100 logs. Logs serve little purpose beyond fleshing out Dead Space 2's story and are lying around everywhere. There are more than 100 logs to collect in total so don't fret about missing one or two.
- Collect Peng (20 GS/Silver) – Find the Peng treasure. Full guide is forthcoming.

Dead Space 2 Trophy Guide – Combat 1
Vacuum Cleaner (30 GS/Bronze)– Decompress 20 Necromorphs without getting sucked out yourself. This will require two consecutive playthroughs (via New Game+) as there are only a handful of decompression windows throughout the campaign. They are identified by a yellow/black hazard bar and a warning sign reading "Future Expansion". When Necromorphs are nearby, shoot out the glass to suck them out into space. You must quickly shoot the flashing red triangle button above to close the window before you get sucked out behind them.

- Shoot the Limbs! (10 GS/Bronze) – Dismember 25 Necromorph limbs.
- Epic Dismemberment (50 GS/Silver) – Dismember 2,500 Necromorph limbs. This may require a New Game+ run to complete, depending on your dismemberment thoroughness.
