Is the Russian version of Mass Effect 2 (pc) any different from the English version other than the box?

 Ok so I bought Mass Effect 2 (pc version) off of ebay, and I got it in the mail today. Everything is fine (new condition, still in original store packaging) however when I looked at the box more closely it seems to have everything but the title of the game in a foreign language (I think its russian). My question is, is it just the box that is russian, or is the actual game a different version from the regular english version (like would it have all the text/voices in-game as Russian?). This is a brand new game so I want to know for sure before I unwrap it, and whether to return it or not.
