The action will take place next week in New York, San Francisco, Las Vegas, Berlin, London and Paris. Disks with Mass Effect 3 will consolidate on the special balloons, which, of course, is unlikely to get to space, but in the upper atmosphere certainly rise. Each disc is equipped with a chip GPS, with which you can determine where it is. Over time, burst balloons, and drives with Mass Effect 3 will fall to the ground, where they will find themselves close to the lucky pick. But those who are not lucky enough to get a gift from space, will be able to buy Mass Effect 3 on March 9.
