Hints & Tips

Easy kills
Just pick up an enemy with TK. Now throw him towards you or against a wall or something. While he is on the floor, shoot him with the tranquilizer gun. He will not bother you any more.

Quick reload
In order to skip a long reloading wait simply press Punch. This is helpful in close quarters like hallways or small rooms.

Escape level: Boiler
There are workers in orange on the lower floor. Just use Charm to sneak under the pits of liquid connected with pipes. Then use Telekinesis to flip the left switch. The guard will say that the temperature is going up and will fix it after a few seconds. If you keep doing this, on the third time the boiler will explode and two guards will normally come running.

Escape level: Secret weapon
When you reach the end of the board where the car is at, go to your left and down the ladder. When you are there, do not use your projection. Now go down the other ladder. You will see an assault rifle. Then use your Telekinesis ability to grab it.

Experimentation level: Guard slacking off
Simply play the Experimentation level. In the main lobby where you start and kill the guard, reach the computer and exit the panel that pops up. After you do this, you will see a face in a talk bubble icon called "Chat…". When it does appear, immediately read it to find out the guard was talking to someone prior to you getting there.

Madness level: Freed by psycho
Prior to you reaching to Jayne Wilde, you will move through a grid with MANYcells. You can open these cells to cause some disorder. However, if you stand in an empty cell and project yourself out the door and to the switch outside, you can be locked in. Snap back to your body and Vettic will make a comment like "Well that was clever." Wait a second or two and one of the psychos in the cells will run along and pull the lever, letting you out.

Madness level: Bounce basketball
In the beginning of this level there is a shed. In the shed is a basketball the you can bounce with your "powers".

Madness level: Distractions
If you come across a crazy man in the level you can lead him places by using Telekinesis on an object. If a guard does see him, the alarm will go off and they will try to silence him. This is a good distraction, but it will not work on the violent ones in the west wing. Instead, cause disorder by releasing them then use Charm to sneak past them. While there is a all-out war going on, you can easily kill the two guards in the room behind the gate if they have not left. Time your actions and be quick because the guards with the .45s will send them out.

Madness level: Spare CCTV key
When you reach the first hallway three doors down, where the guard is at, take him out. Enter that room. Look up to the window and you will see the spare CCTV key. Simply use your telekinesis ability to get it down and exit the room. When you reach the desk, go left in the room where the locked door is at. Then use the key on the office door. You will now be able to grab the shotgun and use the computer.

Reliance level: See ghost clearly
You will come across the projection of one of the children in this level. If you aim your sniper rifle at this "ghost" when you leave the train and she is curled up in the corner, the child will no longer be transparent and you can see her.

Isolation level: Easy kills
At the beginning of the game when the Feds are attempting to gun you down with their automatics, kneel down behind the desk on the left side of the room. Now Psi Blast the feds. After they have been shot, you can then grab their weapons to use.

Isolation level: Fighting guards
You can also lead the two guards into your cell and lock them in. If you watch them, they will start to argue and in time fight each other.

Projection
When your on the Conspiracy and the Madness levels, you can use the projection to open a few doors and flick switches. You can also possess the guards. If you are close enough to a guard when you have activated the projection, he will flash blue. Then press X and you can go off and kill every guard for as long as your have psyche energy. You can this again until all the guards are killed and all the cameras are unoperable.
