The Simpsons: Tapped Out (Free) is continuing its tradition of nearly monthly updates which began way back in August of last year, and not surprisingly this month’s update celebrates the upcoming Halloween holiday as well as the traditional Treehouse of Horror episode of the show which will air this coming Sunday.

This update includes Spooky Specters which can possess the good citizens of Springfield unless you’re quick on your feet and tap, vacuum, or blow them up with a ghost bomb in time. They’ll leave behind a GOO which you can collect and use to unlock some special rewards. Defeating these ghosts will give you a chance to get some Gremlins which you can unleash into your friends’ towns and can score you some bonus GOO. Mmmmmm, bonus GOO. There’s also an alien invasion occurring, naturally, which you can help fend off by building a Giant Ray Gun and zapping UFOs out of the sky.

There’s plenty more new stuff in this Tapped Out update, including new Halloween characters, new buildings, a new ride to build in Krustyland, new Halloween decorations and of course plenty of new quests. Interestingly, if you do end up watching the Treehouse of Horror XXIV episode of The Simpsons this Sunday, you’ll have a chance to unlock a unique outfit for Homer in the game. If you’re all geeked out over The Simpsons: Tapped Out like so many folks seem to be, check out this latest update and get into the Halloween spirit.
