The Addams Family is a game from Ocean Software released in 1992 for the Super Nintendo and Sega Genesis. It also has a simplified NES port under the name Pugsley's Scavenger Hunt. In this game, it's implied that family members have been captured and are being held hostage by enemies, it's up to Gomez to save them all.
The three authors defeat all the bosses, collecting all health upgrades and saving every family member in record time, which makes for a very creepy, kooky, mysterious, and spooky run.
This run has commentary provided by the authors. They are embedded in the torrents and in the YouTube video.
