The game includes various different minigames. There's story mode where, playing as Homer, Krusty, or Bart, you have to defend the city of Springfield from alien attack. Then, there's another playing mode where you'll control Burns (as a vampire) to defend your mansion.
Finally, there is a two-dimensional fighting mode where you can use Futurama characters like Leela and Bender to fight with special attacks: Leela, for example, can use her laser, while Burns has the ability to turn into a bat.
Simpsons: Treehouse of Horror is a fun action game that is especially perfect for fans of these animated series.
