Lee Aymond.

Hint: Staying human:
After leaving 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.
MeStUp0019.

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.
SoccerplayerD8.

Hint: Faster destruction in the UFO:
Instead of holding R1 to destroy buildings or large objects, tap R1 and the destruction will happen faster without waiting for the recharge.
Command Station.

Hint: Destroying Majestic cars:
Use your PK ability on a Majestic limo. Hold L1 all the 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.
KurejiKarite.

Hint: Mayor statements:
During mission 3, to keep the town people happy when disguised as Mayor choose the following statements.
Dbgarrott.

Tell The Truth
Blame Communism
Tell A Joke
Threaten Communists
Make Empty Promises
Blame Cows

Hint: Convincing General Armquist:
When he asks you about the fair, say "Rowdy kids did it". Then say "Did you catch the assassin?".
the king.

Hint: Mutant thoughts:
If you scan a mutant a few times, eventually he will say, "1... +... 1... =... window".
Josh Sibert.

Hint: Embarrassing Majestic thoughts:
Go to any town and read the thoughts of Majestics that are walking around. They will say embarrassing things like:
GeeForce95.

"I hope the other guys don't notice... Oh what the heck lace feels good under this suit!"
"Why does Silhouette keep giving me these jobs? is it because I hit on her at the Majestic Christmas party? Oh wait scratch that thought. No one is supposed to know she's a girl."

Hint: 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 X to boost away.
Command Station.

Disguise yourself as a human to help you to get around virtually undetected. You cannot be seen by anyone if you are in stealth mode, even the police and the military. When Majestic appears, never get close to them. They will bring it down when you glow red. That does not indicated that you are being jammed; it just warns you if an agent is too close to your presence. Figure out a way to take them out or avoid them. The PK is recommended as a good stealth weapon against them.
Dbgarrott.

Hint: Easy collect brainstem puzzles:
Enter a collect brainstem puzzle. Find out how many you need. Then, stand around extracting the brains and leave them laying there close by. When you have enough, go to the challenge and enter it. You can easily win by doing this.
Grindlerbug.

Hint: 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.
Command Station.

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

Hint: Finding weapons:
When you unlock Area 42, you should see some bunkers that represent bomb shelters. They all have ammunition inside.
Harry Buck.

Hint: Control objects:
When you pick something up, you can control it with the Right Analog-stick.
tallguy.

Hint: Awareness levels:
The awareness levels at at the top of the screen. They are four basic icons. The first one indicates that civilians are aware of your presence and its color should be purple. The second one indicates when the police are sent to investigate, and are on the scene with a yellow car symbol. The third one is a big orange star, which indicates that the military are involved. The fourth one is Majestic, a top secret government agency which has the power of seeing through your disguise and bringing you down with high tech weaponry. When you alerted to the police and the military (the orange star and the yellow police car) you can disguise yourself as a soldier for the military alert level or a policeman disguise for the police alert level. You can just use a normal civilian disguise for the first icon. You can also find hiding places or use your Jetpack to escape. For the Majestic alert, disguise yourself as one of them, but do not get too close or your disguise will deactivate, revealing your alien form. The Majestic symbol is a big red M. Keep moving when you fight them and look for out men in black with big green guns.
Matt David Garrott.

Hint: HoloBob:
Put your target (dot in the middle of the screen) on any human, and press Circle. 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.
Command Station.

Hint: HoloBob when near Majestic:
Majestic will not always jam your disguise if you get too close. This only happens if you are on a mission. Otherwise, you can walk about six feet away from them and they will not jam your disguise.
Josh Sibert.

Hint: 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.
spongebobkid67.

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.
MeStUp0019.

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

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

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

This will help to buy the expensive final upgrades.
Max Santos.

When Pox has you take out the President, just run up, extract his brain. and take it. When you do this you will get 200 DNA. That is the most you can get from a single human.
thannos.

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.
jay.

To probe a Majestic Agent, cycle to your anal probe and charge it. Then, shoot the agent. Do this three times and the agent brain will pop out. It is worth 75 DNA each time.

Shoot a human (normally worth 25 DNA) with the anal probe a few times without charging it, then shoot them with full charge. Their brains may now be worth 50 DNA instead of the usual 25. This is best used at Tunipseed Farm and Rokwell. Farmers and cowboys work the best. This does not always work, and never works on army men and Majestic Agents.

The best way to super charge DNA is to use your Zap O Matic. Zap the person just before they die. Then, hold L1, target the person, and rapidly tap Circle. Their brain should now have be super charged DNA.
Ryan Miller.

During the mission where you are supposed to assassinate the President, instead of shooting him or blowing him up, take his brain. It is worth 200 DNA.
JarJake1.

When you are in Capitol City, go to The Octagon (the place where you fight Silhouette). There should be G-men who are glowing green. They are radioactive. Extract their brains to get about 150 to 300 DNA.
Jo Skeen.

On the Rockwell level at the fair, after you get the woman in the tent let her go to your saucer. Extract the mayor's brain and you will get 200 DNA. This also works at the BBQ at Santa Modesta, but you will get 200 to 300 DNA.
Plank95.

Hint: Easy DNA:
If you need extra DNA or you are running low for an expensive upgrade, go back to the Turnipseed Farm level. Extract as many brains as desired. The Anal Probe Gun is a good weapon for this. Its much easier to use than rapidly pressing the Circle to extract the brain stems of humans, as one charged shot from the Anal Probe will make their brains explode. You need three successful hits on Majestic Agents, two successful hits on the soldiers, and one hit for the policemen. Normally you can choose to extract your brain stem with the probe button (L1) and tapping Circle rapidly to extract DNA faster. However this is not an effective tactic to use as Majestic Agents and soldiers take more concentration to extract their brain stems. Forget the concentration meter and use the Anal Probe Gun. To aim, use the Right Analog-stick and place it over a human. Then, hold R1 to charge up the Anal Probe Gun. Release R1 to fire at the selected target. One shot is all that is needed to take down some humans, but others may require more. However, you have unlimited energy with the weapon.
Matt David Garrott.

Brain extraction and cortex scanning is best done with the anal probe, and not the concentration meter. A fully charged blast from this weapon is all you need to kill them. Make sure it is a direct hit. You can adjust your aim by using the Right Analog-stick. You can do it with the extract ability, but you must remember that the Majestic military and the police require a lot of concentration to snatch their brain stems. The anal probe weapon should prove useful wit them. Cortex scanning can refill the concentration meter and will give you a longer Holobob. Be sure to scan some humans to keep it fully charged.
Dbgarrott.

Hint: Levitation death:
It you levitate a person for a long time, they will die.
spongebobkid67.

Hint: See skeletons:
While playing as Crypto, pick up someone using PK and throw them up in the air (do not push them). When they come back down, shoot them with the disintegrater ray. They will freeze in the air and melt, showing their skeleton.
ginalasseigne.

Hint: 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.
spongebobkid67.

Hint: Anal Probe:
When anal probing someone, TK them just to lift them up. Do not push them or slam; just tap TK and release. This should put them on the ground. While they are on the ground, charge up the Anal Probe fully. When they first start to get up, release the Anal Probe. The brain stem will come out without them running all over. Note: this works best on Turnipseed Farm.
Tombstone.

Hint: Hypnotize faster:
When trying to hypnotize people, rapidly tap Square.
masterpox.

Hint: Extract DNA faster:
While extracting a person (alive or dead), tap Circle quickly. You will get their DNA easier. This is useful against the M Agents and Psi G-men.
ronnie wolfe, Chad MacDonald, and cfittock.

Hint: Extra jet pack distance:
When using all the power in your jet pack, repeatedly tap X and you can get to farther distances.
Kanak Attack.

Hint: Jetpack battery:
Examine the back of the Jetpack when you first take it out. You will see three green rectangles. They will turn red and act as a battery gauge. That is why you cannot fly for very long.
Kyle.

Hint: Fly after Jetpack has run out:
To fly after your Jetpack has run out, quickly tap X.
Mark Boncal.

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

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

Hint: 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.
Johnn Cunningham.

Hint: Learn Silhouette's gender early:
When in Area 42, scan the minds of the Majestic Agents. Eventually, one will have a thought that reveals that Silhouette is a girl.
BIGSILLINGS.

Hint: 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.
CATLORD1993.

Hint: Get on Santa Modesta tower:
To get on top of the Santa Modesta's SMCBS TV station towers, get on top of the station's roof. Then, jump onto the satellite dish and from there, to the slim post. When on the post, jump and use the "Extra jet pack distance" hint to get to 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.
Kanak Attack.

Hint: Protecting the television towers:
When you must protect the television towers from the military, to kill the robots drop two explosives on each robot to kill them.
Skywalker9108.

Hint: Abduction Slingshot:
When you are in Santa Modesta, go into your ship and cycle to the "Abducto Beam". When any form of car is directly underneath your ship, abduct it and go near one of the bigger buildings and keep going. The car will remain against the wall of the building as you go along. When you keep moving, the car will come at you fast but will not hit you. As the car comes at you, release the "Abducto Beam". The car will go flying through the air. This also is an easy way of getting cars to explode against the tall building.
Alex Dias.

Hint: Radio towers:
When you have to defend the radio towers, you will get to use the atomic blast in your space ship. Be very careful. If you shoot too close to the towers it will bring down there health even more.
bwefme.

Hint: Getting a lift:
Enable the "Bulletproof Crypto" code. Go on top of a car (military trucks and tanks work best). Aim your Ion Detonator at the vehicle. Detonate it and you will be shot into the air. You can use your jetpack to fly away.
sariedwards.

Hint: Pound cars into the ground:
Pick up a Majestic car then slam it down on a pedestrian car. It will eventually pound it into the ground.
Remosauto1.

Hint: Movement:
The more you move, the harder it will be for your enemy to it you. Being a stationary target for the enemy is not a good idea. Make it difficult for your enemies by moving side to side. This also works with the shotgun farmers. It is also the best way to fight the Majestic and the military soldiers with rifles. In the saucer you must strafe out of the way. This can save Crypto's life. Avoid the heat seeking missiles. When you see one locking on, take evasive action by moving to the side. It will miss you. This technique requires some practice.
Dbgarrott.

Hint: Have Crypto and camera face the same direction:
Shoot one Ion Detonator. Move somewhere where you will not get hurt by it. Turn in the direction you want everything to be faced. Explode the Ion Detonator manually.
tyler grose.

Hint: Blazing Saddles reference:
When playing In Santa Modesta, as you are defending the television towers in one of the levels, Pox will occasionally say "C'mon Crypto! Do that vodoo that you do, so well!"

Hint: Half-Life reference:
When you are in Capitol City, scan a scientist and eventually you will hear, "I mustn't be late! They're waiting for me in the test chamber! Oh wait, wrong game." This is a reference to the start of Half-Life.
Chase Mooneyham.

Hint: James Bond 007 reference:
At the lab, if you select ship upgrades you might hear Pox say "Here are the keys. And, try to be careful with this one 00- I mean, Crypto".
HaLo2gAmEr002.

Hint: Pinky And The Brain reference:
In the final mission, scan Silhouette's mind. Eventually she will think "What was I doing? Oh yeah. The same thing I do every night. Try to take over the world!".

Hint: 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.
MeStUp0019.

Hint: Village People reference:
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".
Robby Gaskins.

Hint: Literary reference:
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".
Thetaz1991.

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

Glitch: Levitating human or animal:
PK a human or animal and place it on top of the saucer. Enter the saucer and look where you landed. There will be a human or animal floating.
Dylan Rumsey.

Pick up a human and put them on the saucer. Get in the saucer. Once in the saucer you can see the person floating.
Fittocks.

Glitch: Put chicken through the ground:
When at Turnipseed Farm, PK a chicken. Slam it into the ground, then hold Down and walk backwards. The chicken will go through the ground and make a splashing noise.
Dylan Rumsey.

Glitch: Human stuck on movie screen:
Go to Rockwell Drive-In and PK a human. Push the human into the movie screen. They will freak out and become stuck in the screen.
Dylan Rumsey.

Glitch: Put body through building:
At the Rockwell Drive-In, get a human. Majestic Agents work best. Kill him or her with Psychokinesis. Put the human in front of the building's side door and keep using PK Push to transport the body inside the building. Note: This may require several attempts.
cale gubitz.

Glitch: Shoot into the air:
Go to Area 42 at the four way intersection near the airplane hangers. Stand behind an army truck when it is near the center of the intersection. Wait until the troops inside it begin to exit, then shoot a Ion Disintegrater. You should be shot into the sky, but not killed. Pox will then bring you back to the mother ship.
Jesse Thornell.

Glitch: Transport to mothership:
In the Area 42 level, go to where the hangers are in your saucer. There should be a big plane. Use the Abducto Beam (R1) on it and do the sling shot, where you put the object behind a building and fly away. When the plane slingshots, keep holding R1and the plane should cause you to fly down below the level and be transported to the mothership. Note: This may require a few times.
Duncan Ferguson.

Glitch: Invisible Crypto:
In Santa Modesta, go to the light house. At the top, go in circles. Crypto will become temporarily invisible.
alex brogan.

Glitch: Lantern G-Men:
This may require a few attempts. Wait for a G-Man to start charging up a circle beam. When he is about to shoot it, zap him with the Zap-O-Matic. If done correctly, then the G-Man should die with green energy around his hand. It will remain there until you disintegrate him.
Liam.

Glitch: Go through roof:
When you are in the Attack Of The 50 ft. President level, there is a small round building to the left of the capital. Go to the building. Go up to the square part just above the steps. Use your jet pack to fly straight up into the roof. You will through the roof. Once in the roof quickly fly forward. You will land on the inside of the roof, and will be safe. Nobody can hit you while you are in there, but you can run straight through the walls and use your jet pack to jump up on the roof, giving you an advantage.
really bored kid.

Glitch: Hoverboarding:
In Rockwell, go to the drive-in movie . There should be a car somewhere nearby in the drive-in. PK the car and throw it at the screen. Part of it should break off. PK the piece and bring it to an open field with no people around. Jump on it and PK it while you are on it. Start running while you have it PKed. It should act as a giant hover board. Note: There is a certain spot you have to PK and run on it or you will fall off. Also, do not turn too far to the left because it is the flat side and you will fall off.
john smith.

On the Capitol City level, you can make your own hoverboard. First, purchase all of the Psychokinesis upgrades from the Mothership. Travel to Capitol City. Enable the "Bulletproof Crypto", "Ammo a Plenty", and "Deep Thinker" cheats. Go to the Washington Monument and throw tanks and army transport trucks at it until it breaks. Climb to the top of the larger piece and lock onto it with your mind. Pk it so it lifts up with you on it. You can now leisurely float around the city on your "hoverboard". Note: Stay away from the water; if the piece falls in it will be gone for good.
