Screensaver
Allow the game to idle. Eventually the screen will turn black and white and elevator music will play in the background.

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

Faster Destruction in the UFO
Instead of holding [R] to destroy buildings or large objects, tap [R] and the destruction will happen faster without waiting for the recharge.

Getting away from the law
Forget running away from the authorities with short legs. Use your jetpack liberally to fly away. Press [Left Analog-stick Forward] and hold [A] to boost away.

Finding more probes
Probes are necessary to get upgrades faster. 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.

When you are in Capitol City, you can find about ten probes by the broken Pentagon.

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

HoloBob
Put your target (dot in the middle of the screen) on any human, and press [B]. In order to maintain your HoloBob, you must read the thoughts of the humans walking around. You can read the same person's thoughts repeatedly to keep your mental powers charged.

Better DNA value
Every chance you get, do not kill the 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.

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, no matter what.

Mystery Agents' brain stems are worth 25 DNA points most of the time, whether dead of not.

The Psi G-Men are worth 150 DNA alive and 75 DNA dead.

After you beat 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

This will help to buy the expensive final upgrades.

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

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

Hypnotize faster
When trying to hypnotize people, rapidly tap [Square].

Staying human
After getting out of your UFO, aim at a human and press [Circle]. 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.

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 [Circle].

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

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

Ride the Washington Monument
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.

Plan 9 From Outer Space reference
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.

Glitch: Extra robot arm
When done with a mission at the capital city, enable the "Deep Thinker" and "Bulletproof Crypto" codes. 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.
