The plot is based on the comic Cadillacs and Dinosaurs and takes place in the 'City In The Sea' and its neighboring nearby jungle. Players can also find and use various firearms, throwing weapons such as rocks and explosives, and melee weapons such as clubs. Each character has two special moves including one that depletes a character's health upon contact with an enemy and when two or more players play together, they can trigger a team-attack. In Cadillacs and Dinosaurs, the player has access to several attacks.
The game's titular dinosaurs make appearances as neutral characters that may attack both player characters and enemies. There are four playable characters, each with their own strengths and weaknesses: Jack (balanced type), Hannah (skill type), Mustapha (speed type), and Mess (power type). Up to three players can play at once, guiding their selected characters through eight stages, battling various enemies and bosses.
