Yes, that looks like Tyler Bailey...

As promised, the transcript to the screaming German video. I've included the most common and most ridiculous utterances...
"Starte das Speil du Hurensohn!" - Start the game you son of a whore!
"Ich sage es dir nur noch einmal..." - I'm only going to tell you one more time (threatening the screen)
Singing: "Jetzt geht's los, jetzt geht's looooooos" - Here it goes, here it goooooooes
After running out of breath... "Positiv denken, positiv denken" - Think positive, think positive
Crazy laughter... "Jetzt geht's los... friss das du Hurensohn, friss das, ich habe ihn umgebracht... WOOOO!" - Here it goes... gorge on that you son of a whore, gorge on it, I killed him! WOOOOO!
"WOOOAAAH, WOOOOAAAAH, FEHLMELDUNG, WAS? WOOOAAAAH!" - scream, scream, Error screen, what? scream some more
Finds and replaces key on keyboard, "Haha, ich brauche keine Hilfe, ich brauche keine Hilfe" - Haha, I don't need any help, I don't need any help
The rest, before the final freak out, is a combo of the above statements, lots of "Hurensohn" and a few "I will shoot and kill you alls" mixed in. He may also throw a curveball in there, Hurengeschwister, which I have never heard, but would be "sibling of a whore"

Now that I look again, this is quite possibly staged as the bashing of the keyboard in Rd. 1 wouldn't facilitate much killing on his end later on. Still might be fun to see if you can pick out the German phrases, and be sure to practice at home.
