Hint: Mind Control Suicide:
Hold L3 + R3 while controlling someone else's mind.

For the mind control suicide to work, you must hold L3 + R3 for several seconds. After awhile, the enemy will start to kneel. After he kneels, you can exit his body, but he will still commit suicide.
Bob Hand.

Hint: Defeating Jov Lenov - Master of Mind Control:
TK the MPs that Lenov is MCing and throw them at the machines. After you destroy all of the machines, Lenov will fight you. Just use your gun or TK the MPs and throw them at him.
Wurd.

Hint: Defeating Edgar Barret - Master of Telekinesis:
TK the objects on the conveyor belt and throw them at Barret. After you get his health down a bit, he will take the fight outdoors. Just do the same thing until you defeat him. Watch out when he throws the large crates and boxcars at you. They can kill you in one hit if you are not careful. Wait until he rests, then nail him.
Wurd.

Hint: Defeating Wei Lu - Master of Illusion:
Use PK on the statues then shoot them. After you destroy all the statues, Wei Lu will transform into a huge three-headed dragon. Destroy all three heads to defeat her. It is best to go to the back of the room and use the assault rifle if possible.
Wurd.

Use TK to throw the jars on the statues. To kill the monster itself, run to the room where it came from and keep using Pyrokinesis.
Sidney Ferreira.

Hint: Defeating Marlena Kessler - Master of Pyrokinesis:
Use TK to pick up and throw the canisters at the large gun. To avoid the huge blast, go to the back of the room. You will notice some glass things that popped out of the floor. Get behind one of them. Once you destroy the huge weapon, Marlena will fight you. TK the canisters and throw them at her to defeat her. Note: The canisters will refill after you use them all (they must all explode). Also, make sure you are on the side that she is on.
Wurd.

Hint: Defeating Nicholas Wrightson - Master of Remote Viewing:
Destroy all the screens in the room to defeat Wrightson. You can only destroy them when they are firing. Just dodge the ray and shoot them. Be sure to also, avoid the Aura Beasts in the room.
Wurd.

When the fight starts, run forwards and to the right hand side of Nicholas Wrightson, so that you are positioned against the wall and can see the screens the he uses to fire laser beams at you. When there, use your machine gun or assault rifle on the screens. They will explode, and you will take little damage. The screens cannot hit you without hitting another screen. Watch out for Aura Beasts, but they are not too difficult. It is possible to defeat this Boss in under thirty seconds, even under the elite difficulty setting.
RaphRapture.

Hint: Defeating The General - Leader of The Movement:
Use PK on each Monolith pillar (the spinning things). Upon destroying them you can collect up to six orbs (which will be scattered around the room) for your new psionic weapon. Once The General gets to full health, the fight will begin. Just shoot him with the psionic weapon to damage him. You can refill your psionic weapon's ammunition by getting in the center of the Monolith. Note: Make sure to quickly get out from the Monolith once your ammunition is refilled. Also, when The General goes invisible, just use your Aura View to see him.
Wurd.

Hint: Defeating Zombies:
If you have a shotgun, just shoot them in the head. If not, MC one with a shotgun and use him.
Robin1AF.

When fighting the Zombies, simply use Mind Drain to kill them.
B~Smoove.

Hint: Mainframe code:
On the level where you fight Jov Leanov, there is no exact code to get into the mainframe. The code is different in each game. The way to get the code is to use your remote viewing and go into the room all the way at the end of the hallway. Once your remote viewer is in it, you will see people standing at a computer. Look at the computer screen to see the code needed to access the mainframe in big numbers.

Hint: Levitate yourself:
To levitate yourself in a way, get on to an object that you can levitate, such as a box. Aim down and hold Triangle to lock on. Press L1, and the box will levitate with you on it. To go higher, keep holding Triangle and press L1 continuously at the correct time. You should get progressively higher. This is useful for getting to high and far places.

In order to levitate from the ground, stand on any object such as a crate, barrel, bench, etc. Perform the TK ability while standing on the object. Make sure that the crosshair is lined on the object. You will begin to levitate with the object with the Right analBog-stick as if you were controlling an object from afar. Make sure that the object is not a wooden crate or an explosive barrel, as they are fragile to gunfire and other objects. This tactic can be used to make the "drop" on enemies below. The only problem is that you cannot use any other mind powers.
FuryThun2004.

Hint: Instant kill:
To instantly kill someone with a shotgun without having to aim at their head, use TK to levitate them as high as possible without multi levitating. Walk almost, if not directly under them, and fire the shotgun. It should automatically aim at their head and blast it off.
Lex Meek.

Hint: Mind Control and TK MP3s while they are still alive:
TK an item that can be thrown, or anything that can knock an MP3 down such as a box or crate. Throw it at the MP3. While the MP3 is on the ground, use either TK or MC to lift the MP3 or Mind Control him. While in mind control, if the MP3 has a weapon other than a handgun, commit suicide with the MP3. His head will explode, which will not happen even if you get a headshot with a shotgun.
Billy Grant.

Hint: Use Psi powers on the robot in practice mode (Psi training):
Hit him in the back of the head with something, then use powers (MC, Lev.. etc.).
dustin bowen.

Hint: Alternate suicide effects:
If you MC somebody and commit suicide (hold L3 + R3), they will have different effects depending on the weapon.

Handgun: They will simply die with no special effect.
Machine Gun: Head will explode.
Assault Rifle: Head will explode.
Shotgun: Head will explode.

If you are MCing a Dockworker or a Blue Suit, they cannot commit suicide because they do not have weapons, even though some Dockworkers hold knives.
Billy Grant.

Hint: Exploding enemies:
When you kill somebody, take a sniper rifle and aim around his body until you find one of his grenades. Zoom into it, then shoot it. His body will explode.
PuertoRicnBoy77.

Hint: More Psi energy:
Sneak up on an guard and use the Mind Drain power. You can almost fill your Psi bar up when it is completely empty.
BadboyH20.

Anytime you get to a checkpoint and are short on health or energy, save the game. Reload it to get full health and energy.
Christian Calderon.

You can simply Mind Drain anyone to regain Psi Energy. You need to have at least a little Psi energy for this to work, or enough to get someone on their back. Use Telekinesis to throw him down and Mind Drain when he is about to get up. If you want a more gruesome death, wait until he is just about to get up and his head will pop, just like an ordinary Mind Drain at the end.
PETROS483.

If you cannot sneak up to an enemy and drain him, throw him at a wall, object, or the ground. When he starts to get up, use Mind Drain. This will almost fill you Psi Energy completely if you are empty.
Agent Smith.

Hint: Special skin abilities:
Some of the character skins have special abilities. For example, there are masters of Psi powers such as Barret, Pyro, and Lenov. They can do many more things than Nick with their powers. If you were to unlock their skins, you will also get those abilities.
PETROS483.

Edgar Barret: Can carry all MPs, has the ability to carry very heavy objects (boxcars, trains, crates, etc.; preferably in the Barret boss fight), Psi drains slower than usual.

Jov Lenov: Can Mind Control anyone, can make anyone commit suicide at anytime, Psi drains slower than usual.

Marlena Pyro Skin: Her Pyrokinesis can burn faster, fire goes through most objects or until it hits a wall, Psi drains slower.

The General Skin: Has all the powers listed above.

Hint: Elevator music:
On the level with Wei Lu, while you are in the elevator the music playing sounds like "With My Mind" by Cold.
Byrd5556.

Hint: See dead enemy spirits:
You can actually see the spirit of the enemies that you kill. To do this, you need to have the Aura Vision ability. Then, kill a guard while in Aura Vision mode. You will see their "spirit" float up, cartoon-style.
Tonickboy.

Hint: Flying corpses:
Find a dead body and use Mind Drain. Instead of holding Mind Drain, repeatedly tap it and the body will fly into the air.

Glitch: Med kit mix up:
During the Boss fight with Barret, he will get angry and say that he wants to take the fight outside. After he rips apart the trash compactor and you slide down, look around for a large med-kit to the left. However, when you pick it up, it becomes a Psi-revival item.
MonkeyFishG130.

Glitch: Kick billiard balls in Psi Pool mode:
When in Psi Pool mode, instead of trying to blow up the barrels and objects to move the billiard balls, you can actually kick them. To do so, put your character about two to three feet away from the billiard balls and press Kick/Punch until he does the soccer kick. If done correctly, it will send the pool balls flying.
Tonickboy.

Glitch: Freeze game:
As soon as you enter the level with the Marble Atrium and sentry gun, there should be two pillars on both sides of the double doors. Aim at one. The reticule should turn yellow. Press L1 to try Telekinesis, and the game will freeze.
