Steam News announces the North American availability of the digitally distributed Terminator Salvation game, which should also now be available at North American retailers. Word is: "Terminator Salvation, the new third-person shooter that takes place two years before the events of the upcoming film, is now available for purchase on Steam in North America, and will be available soon in other regions." Unfortunately, this has not gone smoothly for everyone, as ValiantOne points the way to this forum thread where a number of users are reporting an Installshield installation error with the game, which some users have been unable to resolve, though a workaround has been posted that has worked for some.
