Tully Alford has taken control of The Addams Family Mansion and imprisoned Morticia, Pugsley, Wednesday, Grandmama and Uncle Fester. The player controls Gomez Addams as he attempts to save them. They have been stowed away in various locations in the mansion and are protected by a boss of some sort. Thing provides hints on gameplay.
Gomez starts outside the mansion, but once inside, can move from level to level in any order. The mansion is full of secrets, hidden passageways and side levels and bosses. Gomez dispatches enemies by simply jumping on their heads. He can also throw found objects at them.
The game did not have a save system, but instead bore a password system. Completion of various stages would reveal passwords, enabling the player to resume where they left off.
- Snowman - "a cold, but not heartless man," he seems to be made entirely from snow, with a rotund body, muscular arms, and eerie, orange, glowing eyes. He is also able to roll into a giant snowball. Thing's hints say that the Snowman lurks in the Deep Freeze. When he is found, he attacks by throwing snowballs at Gomez. After he is defeated, Gomez earns a Heart Power Up. Unlike other bosses, he does not guard a family member.
