In the year 4122 a Nanosaur was sent into the past to retrieve the unhatched eggs of ancient dinosaur species. The mission was a success, but Rebel Nanosaurs have stolen the eggs and taken them to off-world bases. Now a pterodactyl Nanosaur has been sent to these alien worlds to battle the Rebel forces and bring back the stolen eggs.
Nanosaur 2 is a continuation of the original Nanosaur storyline, yet this time you get to fly a pterodactyl who's loaded with hi-tech weaponry, and the game is much larger than the original 1998 game. In addition to the three level adventure mode where you blast enemy dinos and save eggs, there are also six two-player levels including racing, capture-the-flag, and battle.
