Is there a manual version of the patch? I access the internet through a USB mobile broadband dongle, I can't afford to download a large patch at home, I have to download from a public library.

Further more, who was the [censored] mongoloid who decided it was a good idea to make steam a requirement for a game that is entirely offline?

There is, it's an unofficial release. You can find in online but I'm not allowed to say where.
