The game takes place on an island with dense jungle, fortifications, and volcano areas, where players must fight against thirteen different types of dinosaurs, including velociraptors, pterosaurs, triceratops, and tyrannosaurus. The player has access to various weapons, such as a civil war rifle, crossbows with explosive arrows, and a futuristic plasma rifle. Additionally, there are stationary turrets available to defend against large hordes.
The game features two main modes: regular story mode with twelve levels and survivor mode, where players can fight an endless wave of dinosaurs. In the regular mode, scattered pieces of new weapons can be found, which become available in the survivor mode once fully assembled.
