Activision's DJ Hero computer game was a big hit when it was launched in 2009. It provided gamplay like that of Guitar Hero, but for the wannabe DJ as opposed to the brooding rockstar. This month sees the release of DJ Hero 2, which is packed with lots of exciting new features to keep players on their toes. One of the new features in the game is the inclusion of Novation's Launchpad in the on-screen gameplay.
