Play as characters from the We're Back , a game based on the preview trailer of the Spielberg animated movie. Run and jump through various levels, defeating Dr. Screweyes. Every second level is a side-scrolling platformer where you take on the role of human kids Cecilia or Louie, moving through obstacles to reach the end of the level. These levels are set in different New York locations, including a TV studio and a circus that wants to keep the dinosaurs as an exhibit.
The gameplay involves switching between 3D levels where you play one of the dinosaur characters, such as skateboarding on the back of a pickup truck as Rex or flying over central park while collecting balloons as Elsa. This is one of the earliest Genesis games with 3D gameplay.
