DEMO Hint: Sneak Peak

Note: this cheat works only for the demo... In the first demo mission after killing the three guards in the second area press the red button turning off the lasers at the next door go through the door then you will see another door in that hallway. When you try to open it, it says "door locked for demo" simply use remote view (up on D-pad) and you can pass through the door and explore what the actual game's first level contains.

Hint: 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:

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.

In the Fusion Tower,I found that fliping the switches in the order of K-1, K-4, K-2, K-3 also works to shutdown the reactor. I realize that is the reverse of anothers suggestion, but this way you don't have to worry about the people in the reactor chamber trying to kill you. Also, this way you don't waste as much Psi-energy if you flip the first two switches yourself, go to K-3 and Mind Control a guy to flip K-2 for you.
