My brother came home for the weekend, which was nice. It turns out that he also bought Portal 2, as well, so I managed to get over 9 GB of the files from him, bypassing having to download those 9+GB and racking up a massive internet bill. After he left to go back to University and his new job, I got steam to fill in the blanks, and got to playing.
Now, I'll be honest here. At the end of the boss battle with [censored to protect spoilers], I was just shooting idly. I thought "Well, I don't know what else to do, might as well shoot the [censored]." I completely forgot what the Conversion gel was made of. Anyway, Brilliant game, well worth the wait, and I encourage anyone at TWHL who hasn't yet played it to get it. Next stops, the SDK and finishing the rest of the commentary.
tl/dr:
Finally got my hands on the content for Portal 2, which I preordered off steam shortly before release, played it, was great.
