I wrote this two weeks ago: »›The game should automatically prompt for the update when using a LIVE profile‹ But isn't this outdated ? Does the client still update games, I doubt this somehow.«
Now there is also the following sentence: »The Steam version is unpatched and will also prompt for the update.« I can not confirm this. I do not remember any prompt, when I played the game and was surprised, when the IP here added a patch.
