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.

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.

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. 

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.

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.

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.

Fusion Tower Shut Down:
In the Fusion Tower, there are four rooms: K-1, K-2, K-3 and K-4. The goal of this 
puzzle is to hit these switches in order. Each room contains one switch. You need 
to flip all four of these switches to overload the fusion reactor and move on to the 
next area. Okay. You start off in room K-1, but don’t hit this switch! They must be 
flipped in this order: 

K-3 
K-2 
K-4 
K-1 

Now, while you stay hidden in K-1, mind-control a bad guy and have him run to 
room K-3, then to K-2 and finally to K-4. You're psi-energy will drain pretty fast 
while you're doing this, and of course with every switch you flip, the fusion blast 
becomes faster and more powerful, so be patient. It takes practice, but you'll get 
it. After the first three are down, all you have to do is flip the last switch in K-1 and 
you're done! But watch out for the meat-puppet soldiers that come charging in the 
room. Dispose of them (and anybody else that gets in your way) and run to room 
K-3. A door has now been unlocked.  

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 Y to lock on. Press L, and the box will levitate with you on 
it. To go higher, keep holding Y and press L 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.

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.
