Hint: Getting the Fixer Battery:
Go to the large room with green barrels and a bloody floor. Go to the left. There is a big tank with gears on top. Use the Machine Cog. An FMV will begin and reveal some clues. Notice the door and the walls. You must go to the room at the very start of the game -- it is a long walk from here. There is a Fixer located there. Kill it to get the Fixer Battery.

Hint: Defeating Scanner:
Scanner is the freak with a hole on his forehead who calls Hana and Rain "Kitty". Lure him towards the electrified waterfall. Press L1 to do a 180 degree turn. Run towards the center and hit him hard. He will get toasted. Repeat this three times until he is well-done.

Hint: EMP:
The EMP is one of the best defensive weapons at the beginning of the game. It is located to the right of the yellow key card door in the shadows at the very beginning, when you first control Hana. The EMP temporarily shorts out the electrical circuits of the fixers for a short while using a Electro Magnetic Pulse. To use it. simply equip it and hold down the fire button until the high pitch sound from the EMP is at its loudest. Then, release. The EMP uses electrical charges instead of ammunition -- you can use it as much as needed.

Hint: Extra wrist weapon shots:
The wrist weapon Rain has to use during game (when she is wearing the radioactive suit) normally fires three times. You could make it fire up to six times by first firing the initial three shots while standing/running and the next three when crouching.
