As the story develops through the game, you'll have to get past tons of security measures that run the gamut from a simple firewall to pirate someone's computer, to more serious measures to get into a bank's database.

Hacker Evolution Duality is a pretty special title that requires you to have patience and respect for the stories of hackers if you really want to get the most out of the game.
It's not the full game.
