Video game developer Left Behind Games has announced that it will integrate links to the iTunes Music Store in an upcoming game, allowing gamers to purchase music they hear during gameplay. The game, “Left Behind: Eternal Forces,” is a real-time strategy game based on the best-selling Left Behind book series. The developer said that clicking a music link will pause the game and launch the iTunes Music Store. After the song is downloaded, gamers can resume action or customize their playlist and listen to the newly downloaded music while playing. The game is scheduled for an October release.
