As a 16-year-old kid in a normal town, living a normal life, everything is boring as hell. Walking home, some guy comes up to you and says:
-Kid, you don’t know me, but I know you, I’d tell you about me and where I come from but you wouldn’t believe me. I don’t have much time. Take this HackPad,use it to stop Sky… Use it to save the world when the time comes. Right now, just learn how to use it, and keep it with you at all times. Go hack your way up kid! I believe in you!-

Chapter 2 High School Hack

So here you are with this cool HackPad and a lot of time on your hands. Your grades are not so good, let’s use this HackPad to give them a little boost.
A High school grading system cannot be that hard to hack with this thing, right?

Chapter 3 Jailbreak

A good friend of yours comes up to you with his brand new phone, asking if you could Jailbreak it. He’s pretty techsavvy, so you ask him why he doesn’t just go on the web and do it himself. He says no-one has managed to crack the security on this model yet.
Sounds like a job for your HackPad.

Chapter 5 Corrupted

Wikileaks is awesome . You would love to be part of their team and expose corrupted politicians. You already joined a bunch of forums to see what they’re up to. Right now they’re trying to prove that an influential politician is involved in drugs and weapon trafficking in third world counties.
This is your chance to use your HackPad for justice, all you have to do is figure out a way to infiltrate his emails…

Chapter 6 Cyber Attack

You try to help the world by exposing a dirty politician and all you got in return is a stay in jail. What were you thinking? You’re going to trial in a few days, and they’ve got an army of lawyers against you…
phone rings
-Who is this?
-Hey kid, this is Agent D., FBI. Look, we know you’re not a bad guy, and you’re in a pretty messed up situation right now. We might be able to help.
-Really?
-See, we need more hackers like you around here. So if you’re willing to work for us, I’ll pull some strings to get you off. What do you say?
-… Do I have a choice?
-Sure, either work for us or spend the next 10 years behind bars.
-Deal, when do I start?
-Right now. We got these guys hacking our systems as I speak. It’s driving us mental. Stop them and you’re a free man.

The robot has been neutralized by your virus and dismantled by the FBI. But somehow, the AI that was running it managed to replicate itself across hundreds of data centers, unnoticed… Until today.
It calls itself Skynet, and it has an army of robot marching across the world to terminate the human race. You can hear them outside the building. To stop them, you have to attack the source directly. You must create the most powerful virus you’ve ever made. And you must act fast.

Wiah, you stopped skynet. That was… freaking stressful!
You hate this pressure, the job is becoming too much for you. You want to quit and go to a quiet place where you can just relax and play video games all day. You wonder if you can play games on your HackPad…
You’ll probably have to write the games yourself… let’t see what you can do.
