I was running. So fast. I went through this orange ring of light, and found myself being launched through the air like a missile.
"come back! there will be cake!" Wheatley boomed. There was no way i was going back. I've been locked up too long, far... too... long!
I was cornered.
Maybe i should tell you my life story.

Ever since i could remember, i've been tested. Tested even more, and more... Constant tests. Some were harmless, some improved my eyesight, strength, and agility. But, Not all the tests went properly. I remember when i woke up feeling like i died. It was terrible. Yet that cold hearted bitch wanted me to test even more. Either way, back to my story.
One day, I woke up in my little cubicle. I rose, and walked up to the painting for the mental stimulation test. Soft jazz music played in the backround, as if trying to make me more intelligent. The smooth, white walls giving off a slight, radiating light.
*BAM BAM!* "mind if i come in? Nevermind. I'm just a robot. I wont peak!" said a robotic voice, almost with an english accent. Wait. What's an english accent? Oh well. I'll ask him later.
A white ball with a blue eye launched his way in on a guide rail, and went straight into the roof. I felt my room lurch forward. I must've hit my head, because when i woke up, i was surrounded by vines, leaves and other things on this testing facility. What happened to me?
I stood up, and searched, to see if i could find a way out of here. Odd, some panels were black, others where white.
I saw a small handheld gun. I picked it up, and examined it. I know i've seen this thing before. Instinctively, i tried pulling the trigger. Nothing.
I threw the gun. A beam of blue light lit up the dark passage, and landed on a white panel. A blue, obscure oval lay on the panel.
I picked up the gun again, and pulled the other trigger. An orange oval hit the panel next to it. Except, now, when i looked into one of them, it was like looking through the other portal. strange.
I placed my hand on the blue portal. VWOOP! i saw my hand sticking out the orange portal. "GAHHHHHHH!" i screamed, not knowing that i could actually perform vocal actions.
Odd. it didn't hurt.
"Oh, there you are. You murderer. Now, we can do more tests." said a robotic, girlish voice.
i attempted to speak. "Wgghggho arrear youou?" i managed out.
"I am GLaDoS. You murdered me. don't you remember? oh yeah, thats right. You're too dumb to remember. I'm sorry."
she said, offensively.
(i'm not going to write the entire story, due to spoilers.)
And that's how the entire journey began.

Now, back to the ACTUAL story. Not just the back story.
"WHEATLEY!" The potato GLaDoS said, while it was on the Magnesium strip of the portal gun.
"You're going to cause a meltdown! put me back in, now! don't let him blow us up!"
I just... Gah. I couldn't handle the stress.
I looked down, a massive, undeniably endless pit below me.
"i'm jumping." I said. Amazed i could talk!
"NO! DON'T DO IT!" The robotic voices said together.
"You'll kill me with you!" said GLaDoS. "At least put me down first!"
"DONT JUMP! WE NEED TO PERFORM MORE TESTS!" Said Wheatley, aggravated at my statement.
I shot down straight to the bottom. it took about five seconds, but i heard a portal open.
I shot a blue portal at my feet. I fell immediately through.
Woah.
