A few hours ago Tapulous (now part of Disney), released a major new version of their iPhone hit Tap Tap Revenge: Tap Tap Revenge 4 is now live in the App Store, and it’s free. This new update is the most important one since the original release of TTR 3 and all its spin-offs, and it features lots of new functionalities, songs and graphics.

First off, the app now sports Retina Display graphics and it’s got Game Center integration. TTR now has global leaderboards to see who has the best scores worldwide, a “like” button to see who else likes the same songs as you and sharing on Twitter, Facebook and email. As far as the built-in community tools go, you can create your own avatar and buy accessories and clothes in the game stores, have chats and private messages with other users, engage in online battles and download free tracks every week.

Speaking of which, Tap Tap Revenge 4 comes with 100 free songs from artists like Linkin Park, Taio Cruz, Metallica, Nicki Minaj and My Chemical Romance, plus premium content from the in-app store. The song selection is pretty huge and should contribute to the game’s replay value. The new user interface is cool although a little bit cluttered in my opinion, the app is free but there’s ugly in-app advertising in the main screen. It kind of ruins the whole feeling of the game – still the Retina graphics are really shiny on the iPhone 4.

Tap Tap Revenge 4 is available for free in the App Store. Full changelog and video below.
