In the latest issue of GameInformer, the cover story was devoted to the upcoming Portal 2. Portal 2 is set to release this holiday season as a full retail game which means it will be retailing for $60. In order to fit the $60 price tag, a two player co-op was announced alongside the campaign which is set to include new characters and, “brand new areas of Aperture Science Labs.” Notably, by looking into the orange portal on the cover, a glimpse into the outside world is seen.
