Posts from Russian language pack for the Steam version.

Could you please tell me where I can download the Russian language pack? And if I use it, will I still be able to play with a friend who has the English version?

And one more question: how do I launch the game in windowed mode? I found a solution online that involves changing a "1" to a "0" in a certain file, but then the buttons or cursor shift slightly downwards, causing misclicks.
