SCANNING VERSUS HACKING



***********************


From the very first Mission all the way to the last, you are presented 
with the option to SCAN your Objectives or to HACK them.

In certain Missions, you are required to HACK specific computers. In 
essence, it seems difficult to do up close (because of enemy sentries 
or Cameras) but there is a second option available. 
That option is the EEV inside the binoculars that Sam uses.

Click on the Right Analog Stick to enter Binocular Mode. Focus the 
square reticle onto the Computer screen or RETINAL scanner and it will 
start scanning through a wireless link. 
From there you can hack the computer from a safe distance WITHOUT 
having to physically use the PC itself. Remember, the choice is yours.
