As a publicity stunt for the March 6th release of the game, Mass Effect 3 publisher Electronic Arts will use weather balloons to launch early copies of the game high, high into the sky (but not actually space) next week and encourage gamers to track the packages via GPS and find them when they land. Unfortunately, the launches will only take place in New York, San Francisco, Las Vegas, Berlin, London and Paris, so if you live anywhere else you'll have to pack up your bags and move to one of those cities by next week. "Or I could just visit." Or you could just wait till March 6th like a normal person.

Thanks to Brian and Wilmersama, who have every intention of finding out where they're launching the balloons from and shooting them down with arrows. I like the way you think.
