CarnEvil is a rail shooter arcade game that was released back in 1998. The gameplay was very similar to House of the Dead, but the game was much cooler stylistically. First of all the guns were shotguns that you could cock to reload and second instead of a mansion and zombies, you shot your way through a haunted amusement park. This game introduced me to Krampus and the main villain had the perfect pun name: Ludwig von Tökkentäkker. One summer in high school my friends, Wirty, Chad, and Josh, spent many quarters playing this game from beginning to end at the county fair.
Check out the intro:
I'm talking about this for Ash Wednesday because I think CarnEvil makes a great premise for an Army of Darkness episode or two. The characters or someone around them drop a token into Ludwig's grave and the carnival rises. I mean it's obvious that Ludwig dabbled in black magic, why can't that black magic be from the Necronomicon? Also, his disembodied head sidekick, Umlaut, basically already has stats in Army of Darkness (via Evil Ash's head in the Once More Unto the Breach adventure).
