you will need to grab it with KENISIS,the location is in the docking bay where your first ship arrived on the walkway over the side barriers,when the other ship docks its on the right side of that ship.so go and get your 3 nodes and a trophy!

In chapter 2 when you go into the air lock you will move through the outside of the ship,theres lockers to collect items travel through to the 2nd set,you will see a moon planet and a dead guy floating in space,just below his feet there is a 10.000 credit drop floating about!use "KENISIS"to grab it before entering the gravity room,or you can collect it on the way back.theres an extra node right there for you!

In chapter 5, when you insert the alien DNA sample into the poison, in that same room over on the desk you'll find a book called "field medicine" with the logo from the USM Valor. This is a few chapters before the Valor even comes into play in the game.
Why would a book from the Valor be located on the Ishimura medical deck before the Valor even arrived

As we all know, guardians take a good deal of ammo to kill. However, 4 out of 5 times you can find one of those red cylinders nearby. (Plasma tanks)

Use your kenesis and launch one of these plasma tanks at the guardian. It should kill it with one try, even on impossible mode. ** IF timed correctly, you can kill the guardian before it spits out those egg things. **

press pause then put in the code.
^ = triangle
# = square

First, you must beat the game on New Game Plus mode, with the Military Suit bought and equipped, and save the game right before the last boss. After the game ends and the credits roll, skip them, and do not save the game when it asks you to. Instead, immediately start a completely new game on Impossible difficulty, and you will start the game wearing the Military Suit.

Save after finishing the game. Then, load your CLEARED GAME save. You will start a new game on the difficulty which you previously beat the game with all you Items, all your upgraded equipment, including 10 extra power nodes, 50,000 extra credits, and the schematic for the Military suit (a LEVEL 6 SUIT that costs 99,000 credits).
