Before you get too excited from the title, no, this is not The Simpsons Arcade you're probably thinking of. Instead, it's a upgraded port of a J2ME game which still manages to be quite a bit of fun, especially for fans of the show. The premise of the game involves some secret plans stored on a USB flash drive which Springfield's illuminati (consequently practically consisting of all the rest of the show's cast) decided to hide in a doughnut and entrust to Waylon Smithers.
Smithers naturally loses the doughnut and Homer gives chase, since it must be a pretty good doughnut for everyone to want it this badly. Using a mixture of a virtual D-Pad and two on-screen buttons you engage in fisticuffs with the various henchmen who are, um, protecting the doughnut. There isn't much to the plot, but given the arcade beat-em-up style of the game there doesn't really need to be.
Characters from the show make up the game's bosses, and scattered between every few levels is a mini-game of sorts where homer either chases or runs from something. The only real variety in the game is from the power ups you pick up along the way, which consist of weapons for you to use as well as other members of the Simpson family coming to briefly help you out.
Here is the first few levels, including a boss fight with Chief Wiggum and Mayor Quimby:
The Simpsons Arcade is a title in EA's holiday lineup and is coming soon.
