I translated the whole thing:
"COME ON!!! I WANT TO PLAY UNREAL TOURNAMENT!!! START THE GODDAMN GAME!!! START. THE. GAME YOU SON OF A *****!!!! I WANT TO PLAAAAAAAAAY!!!!"
"I'm not gonna say it again. Start it. Now."
"WHAT THE **** IS THAT?!?! WHAT THE HELL HAPPENED??? I WANT TO PLAY UNREAL!!!!"
*game starts* (you can here the music)
He lets out a scream of joy at that moment.
(singing) "Here we go. Here we go. Here we goooooooo." *happy dance*
(angry) "PLAAAAAAAAY!!!!! YOU (bad word)!!!!!!!! I WANT TO PLAAAAAAY!!!!"
"It's loading? It's loading. When it's loading.... you always have to WAIT SO DAMN LONG!!!!!" Here comes the high pitched scream and I really can't make out what he's saying. But it's along the lines of "I want to finally play".
(to himself) "Think positively. Just think positively... It's gonna start real soon."
"It's starting." *maniacal laughter* "It's starting! IT'S STARTING!!!!"
more maniacal laughter immediately followed by:
"AAAAAAAHHHH, YOU SON OF A *****!!!!!! TAKE THIS!!!! EAT THIS!!!! I KILLED HIM!!!! WHOO!!!! COME ON, COME ON, EAT THIS!!! ****!!!! ****!!!! YOU SON OF A *****, I'M GOING TO KILL YOU!!!!"
At this point, he gets killed and smashes his keyboard, screaming and screaming. At some point, he starts hammering the right side of the keyboard, going "WTF?!? I AM PRESSING THE BUTTON!!!!" Then:
"Huh? The escape button is missing! The escape button is missing! Where is it? WHERE IS THE ESCAPE BUTTON????" At this point he almost starts crying. This again turns into a maniacal laughter.
"Where is it? Where is it?" *inserts escape button and presses it*
"WTF? I don't need any help! I don't need any help!" *maniacal laughter* (I'm not familiar with UT, but I'm guessing it's offering him some kind of help)
"Okay, Enter button is here, directional buttons are there, all set. I'm gonna finish you now. IT'S NOT WORKING!!!!"
Here's where he's starting to sound like a lunatic serial killer:
"I'm gonna get you. I'm gonna get you." *more maniacal laughter* "WHOA, YOU SON OF A *****!!! I'M GONNA FINISH YOUUUUUUUU!!!!! YAAAAAAAAAAAA!!!!! WHOOOOOOOOOOO!!!!! I KILLED HIM!!!!! YAAAAAAH!!!!! I'M GONNA KILL ALL OF YOU!!!!! YAAAAAAAAAAA!!!!! EAT THIS, YOU SON OF A *****!!!!" maniacal again. "I'M GONNA FINISH YOU!! I'M GONNA FINISH YOU! I'M JUST GONNA SHOOT YOU DEAD. I'M JUST GONNA SHOOT YOU DEAD."
"Whoa, the son of a ***** is shooting at me. The son of a ***** is shooting at me!"
End of transmission. The rest is just him shredding his keyboard to pieces. XD
