Bethesda Softworks is using social media in an attempt to get people riled up for the release of their upcoming game, Rage. They are allowing the mobile games, Rage/Rage HD, to be available for free, normally $0.99 and $1.99, respectively, for an entire week after their fan page reaches 100,000 unique likes. The mobile game is well-received by those who play it, receiving four out of five stars in the reviews. As of the time this post was written their fan page was at 41,515 likes, so there’s still quite a ways to go. The platform version of Rage is scheduled to be released October 4, 2011.
