Does anyone have this on the psp...? anyway i'm stuck at one of the levels... its just after you release Wonder Man from his cell and you got power a door to get out of the room.. there are 16 card readers there and using the power console at the top the room activates a random few at a time... when i bring my character to one of the card readers, it says 'use card reader'.. upon pressing 'square' a few of the card readers light up but some of the rest go off.. Is there some sort of sequence to doing this??...or did i miss getting some item???

Hi! I just solved the trick a few hours ago. You don't need to get anything for this puzzle. All you have to do is to make sure all the card readers are lit, or colored blue.

To do this, you don't have to go to the Power Console too much, just at the start is enough, and then use the Card readers that are not lit up, or are colored black/brown. If you use the card reader, you'll see that square light up, as well as one square above, below, and on either side. This is the main idea.

Now, for the trick itself. Go to the Power Console and keep using it until almost all of the card reader lights are on blue or turned on. After that, approach and use the card readers that are not lit up. Click on them once. If you see that the lights on either side, above and below go out, click it again. If the lights around it remain lit, then don't click it again.

Repeat this process until all the card readers are lit, and you'll be able to open the door. Its more of luck than skill, so take your time, and repeat as necessary.
