Anakin's Hints and Cheats
I have four (4) cheats that will help you out, and a ton of hints. You have to put in the cheats on every single level. Every time you go back to the mothership, either by going there manually, from going out of the invasion site, or after finishing a level, the cheats reset themselves.
Ammo - Press start, hold down L2, and press left, circle, R2, right, R1, square
PK - Press start, hold down L2, and press R1, R2, circle, right, R2, circle
Health - Press start, hold down L2, and press square, circle, left, left, circle, square
All Unlockables - At the mothership, hold down L2, and press square, circle, left, left, circle, square (same as health)
Now for the hints and fun things to do
-Cars and other vehicles, specially the majestics' cars, are bombs that are ready to explode. Grab your Disintergrator Ray and start shooting at a vehicle until you see that it's health is REALLY low. When it is, you can blow it up at the spot, or PK it and fling it at something. Once it hits something, it will blow up and set everything there on fire. You can also PK it and drop it from a high distance on top of something, such as a person, to either kill them, set them on fire, or burn up their insides and bones.
-This is just something that I noticed while playing. Every time you extract someone's brain, you can guess about how many brains you will get by it's color. It is based on the colors of the rainbow, the lowest value being at the lowest color. Here are some of the values associated with those colors.
Purple- about 5-15
Blue - usually 40
Green - usually 50
Orange - usually 75
Yellow - a whopping 150
Red - about 200 I believe. Very rare
-It IS possible to create smoke bombs in DaH. What you need to do is to set a car at the level where it is about to blow up (see hint: flaming fireballs) and leave it there. DO NOT BLOW IT UP. Now you just need someone else to blow it up. I suggest that you stand on top of it while people are shooting at you, as they often miss and hit the car. After they blow it up, leave the burnt wreckage there and it will start to smoke. This does not happen all the time, and sometimes happens if you manually blow it up.
FIRE DESTROYS BRAINS
-Another thing that I found out. When someone is on fire, if there are many cars around, they will usually run right into one and die.
MAJESTICS? WHO NEEDS EM
-The best thing to do while getting brains is to go to a city/town and start causing enough damage to call up the military. Once they get there, you should get in your ship (you don't have to if you have the second PK upgrade) and grab tanks. Dump them on top of people until the Majestics arrive. Once they arrive, kill them (no, you can not disintegrate them) and extract their brains. You will usually get about 40-50 brains per majestic, sometiems you will get 75, even fewer times you will get 150 and if you are very lucky, there may be a red brain in there for you.
-When you are fighting silhouette, she usually uses PK powers to protect herself, and at the same time heal herself. Although it is not proven, you can make her take a shorter amount of time in get barrier by using the Anal Prove on her while she's protected. This has worked for me but may not work for everyone.
