After more than a decade keeping the world safe from all sort of futuristic villains and intergalactic ne'er-do-wells, the Power Rangers must guard the Earth against monsters from its past in this adventure. The evil genius Mesegog is scheming to return the planet to the time of the dinosaurs, and players must guide the three Dino Thunder Power Rangers (Red, Blue, and Yellow) through more than 20 levels of action, exploration, and battle to stop him before it's too late (or is that too early?). Along the way, the Power Rangers will need to make use of their supernatural ninja abilities and their Dino Zords to keep the villain from succeeding in his sinister plan.
