Five Easy Achievments - Dead Space

Howdy folks!

It's been a loooooong while since I've written a review (Since the new game well has started to run dry), so I decided to help you out with a little of an achievement boost.
With one of the easily scariest games in history, Dead Space!

1: Pack Rat
10 Gamerscore
This achievement is pretty simple to do. Store 25 items in the Safe. This can be anything from weapons to ammunition to tools. Remember though, you need a full stack of ammunition in order for the one item to count.

2: Merchant
10 Gamerscore
Again, quite simple. By playing the game, you will come across schematics. Find 8 of them and this achievement will be yours. Remember to check near by power nodes and areas beyond the direction point.

3: Armstrong
10 Gamerscore
Third time's the charm, this one is pretty simple. Shoot 50 items with Kinesis objects; this can be anything that maims or kills. With kinesis, everything around you is a weapon against both Necromorphs and tasks in-game.

4: Surgeon
20 Gamerscore
This time, this achievement isn't so easy. Dismember 500 limbs from Necromorphs. Now this seems like a bit of a task to fulfill, but this can be done in the first walkthrough of the game. Remember to hack off every single limb, including dead bodies, and this achievement can be unlocked.

5: One Gun
40 Gamerscore
This achievement is much more difficult; as it suggests, the game must be completed using only one weapon. That weapon must be the Plasma Cutter, the first weapon you receive. Switching to another weapon will count as a second weapon. There are much larger and more difficult enemies that you will face and many of them require different weapons for different moments. However, an easy way around this is to use rule #1 when it comes to Dead Space. "Hack off the limbs."
The quickest, and most efficient, way to do this is always aim for the legs; this will make nearly all Necromorphs drop and fall, giving you a few seconds to put the creature down. You can aim for the head, but this does not guarantee a kill.

Well, I wrote this entirely from my phone, so I think my typing with a touch pad is getting better, despite the fact this took nearly an hour to do!
Thanks for reading!
