Chaos Theory comuter hacking. I am new at this. What button on the controler do you use to click on the bottom 4 numbers as they light up, and is that how you hack the computer?

Once a number highligts, it means it is one of the right combinations to the code. Press x or click on the number to hold it there. Same way the 3 other numbers are done. But be quick. Once the bar reaches red, the alarms go off.

Usually, you only have one attempt. Quicksave before hacking a computer or a doorpanel.
