Enable the "Bulletproof Crypto", "Ammo-A-Plenty", and "Deep Thinker" codes, then get all
of Crypto's upgrades. After this you can turn into a human and walk around TK'ing
everything.

Stand in an open area on any level and walk forward. Keep decreasing your speed until you
eventually begin walking in place.

Enable the "Bulletproof Crypto" and "Ammo-A-Plenty" codes while on your saucer. It will
not get damaged or lose ammunition.

If you scan a Psi-Mutant a few times, he will say "Algernon... Good mouse... Smarter...
than... Charley". The Psi-Mutant is thinking about the book, "Flowers For Algernon".

Find the monument, then throw cars at it until it breaks into two pieces. Get on the long
pointy piece, PK the middle, and try to stay on.

Every chance you get, do not kill a human before you extract their brain stem. Extract
their brain stem first as it will make the DNA worth more (25 instead of 10). The easiest
humans to do this to are the scientists in the level with glowing cows. For some reason,
if the person that is important to you dies (the person you need to abduct), extract
their brain stem before you return to the Mothership -- the DNA is usually worth more.
Additionally, it is rare to find humans with brain stems that are worth 50 or 100 DNA.
Most humans have brain stems that are only worth 10 or 25 DNA. If you walk around Union
Town, there will be humans with signs on them reading, "REPENT THE END IS NEAR". Those
humans will have a brain stem worth 50 DNA. Also, Mystery Agents' brain stems are worth
25 DNA points most of the time, whether dead or not. The Psi G-Men are worth 150 DNA
alive and 75 DNA dead.

After you complete the game all brain stems will be worth more when you use the anal
probe:



Citizen from 10 to 15 

Cops from 25 to 40

Repent Men (Union City) 50 to 75

Army from 25 to 40

G-Men from 50 to 75 



When Pox has you take out the President, just run up, extract his brain, and take it
to get 200 DNA; this is the most you can get from a single human. To get more DNA from
humans, first use Hypno on them. For example, using Hypno on a town crazy (the one with
the sign) can result in 200 DNA. To probe a Majestic Agent, cycle to your anal probe and
charge it. Then, shoot the agent. Do this three times and the agent's brain will come
out; it is worth 75 DNA each time.

While using the jetpack, quickly tap A to go farther distances.

When done with a mission at Capital City, enable the "Deep Thinker" and "Bulletproof
Crypto" codes. Then, go to the bridge that goes to the octagon. Attack the people to get
the robots to attack you. Use the mind control on the robots and lay them about over the
edge. You can see a robot arm pulling the robot into the water.

While extracting a person's brain stem (alive or dead), quickly tap B. You will get their
DNA easier. This is useful against the M Agents and Psi G-Men.

Pause the game, then hold L and press Black, White, Black, X, Black, White(2). If you
entered the code correctly, a message will appear.

Pause the game, then hold L and press White, Right, Left, Black, Y, White, Black, X. If
you entered the code correctly, a message will appear.

When you pick something up, you can control it with the Right Analog-stick.

Enter a collect brain stem puzzle and find out how many brain stems you need. Then, stand
around and extract the brains and leave them laying close by. When you have enough, go to
the challenge and enter it; you can easily win by doing this.

Scan a cop in the Santa Modesta area and you will eventually hear, "If only I had a
cowboy, an Indian, and a construction worker."

When you are in the form of another person, to make you brain juice meter go down, read
other people's thoughts.

To get on top of the Santa Modesta's SMCBS TV station towers, first get on top of the
station's roof. Then, jump onto the satellite dish and from there, to the slim post. Once
on the post, jump and use the "Extra jetpack distance" trick to reach tower 2. From tower
2 you can also go to the other tower. From that altitude the police, army, and Majestic
cannot see you. Use the Ion Detonator to blow them up. This is best done when aiming down
before jumping; you can then see where you are landing.

Halfway through the game you will experience a level where you go to the drive-in to
switch films with the one that is showing. Watch what is showing before you switch films
to see that the film is Edward D. Wood, Jr.'s Plan 9 From Outer Space.

After unlocking Area 42, you should see some bunkers that represent bomb shelters; they
all have ammunition inside.

Probes are necessary to get upgrades quicker. In order to find them all, make sure to look
high up on rocks or hard to reach places. Your jetpack is essential in getting to the high
places. You may have to get up on the ledge or building, then use your jetpack to fly
higher to get the probe. Also when you are in Capitol City, you can find about ten probes
by the broken Pentagon.

Use your PK ability on a Majestic limo; hold L the whole time. Get a wall between you and
the car, then start running away from the wall until the car smashes into it. Keep
running backwards and the car will eventually explode. This trick can also be used to
take out normal cars and people.

Successfully complete the Attack Of The 50 ft. President level to unlock the following
entries under the "Furon Propaganda" option: Crypto, Phone Home!, Developer Darwinism:
Evolution Of The Game, E3 Booth Footage, and Goofy Screenshots And Voice-Overs.

Allow the game to idle at the mission selection screen and Pox will make various remarks.

It you levitate a person for a long time, they will die.

While trying to hypnotize people, quickly tap X.

After getting out of your UFO, aim at a human and press B. When you have changed into the
human, the bar on the top left corner of the screen will go down. When it is all gone,
you will change back into an alien. If you want to remain human, turn into a human and
while walking around, scan other humans or animals to make the bar on the top left corner
stay up. Additionally, turn into a human then enable the "Ammo-A-Plenty" code. You will
stay human forever. You do not have to scan thoughts to get out of the human body -- just
press B.

"B-Movie Theater" option:
