A big update for id games' Rage: Mutant Bash TV (available in SD and HD versions for $0.99 and $1.99; the latter being for iPhone 4 and iPad) has appeared on iTunes overnight. As John Carmack noted in our recent interview with him, it adds a number of new features that arguably should have been there from day one -- namely Game Center achievements and scoreboards. As the game is fundamentally an on-rails shooter with a strong score attack aesthetic, social leaderboards will certainly make for a more compelling experience.
