It looks like Star Wars: Clone Wars Adventures is having a very happy birthday, indeed. Sony Online Entertainment announced today that the game has surpassed 8 million registered users in the past year!

Season four of the "Star Wars: The Clone Wars" television series premieres on Cartoon Network tomorrow, September 16 at 8 p.m. EDT/PDT. To prepare for the new season, you may want to log into Clone Wars Adventures and play Mission on Iceberg 3 because it bridges the gap between seasons three and four of the show.

The press release also hints at some future game content tied to season four: "SOE is creating a new mini-game Aquatic Assault, a top-down 2D action game set in the Mon Calamari battle depicted in the premiere episode of season four. Players will take control of Kit Fisto and his Diver Propulsion Vehicle and attempt to defeat waves of enemies including Aqua Droids, Quarren and Karkaradon."
