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.

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

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.

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

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.

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.

Pause the game, then hold L and press Black, White, Y, Right, White, Y. If you entered the
code correctly, a message will appear. Your concentration meter must be above 0\% or you
will not be able to use any of your mental abilities.

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".

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.
