Subtitled for those who have difficulty understanding English, but are willing to learn ;)
In-game subtitles occupy a rather large portion of the screen, so I decided to make a decent subtitle.

The Turret Opera part is not subtitled yet, due to a lack of official lyrics.

Recorded with Fraps, only because a freaking texture issue in the game:
while recording a demo the Moon's texture disappears, leaving the Moon entirely black, plus there's a problem with the patch of conversion gel under Wheatley.
