Simpsons Treehouse of Horror pays homage to the classic game with beat-em-up gameplay and an alien invasion storyline.

Gamepads are supported, and all keyboard controls can be customized and sound and video options as well.

Each level gets progressively difficult, and just when you think you have it down pat, the boss appears. A similar, difficult character will also appear in the next level. Watch for random cans which give you a power-up donut. You're going to need it. The game does a good job of progressing slowly. You'll want to know how to block and duck after the first level. We had a lot of luck with the dive and punch method.

There are also bonus games to be found including:

Reclaim Burns Manor: Where you are Vampire Mr. Burns, and you must stop criminals from looting your mansion
Tournament mode: Where you must face enemies in one on one combat
Family Guy: where you are Peter and see the events that unfold before he and his family are teleported to Springfield
Gallery mode: special images for your viewing pleasure

Beat-em-up games can usually bore us pretty quickly, but there's enough here to entertain for hours.

The developer put this game out for free to promote his other games so be sure to stop by his website.
