Pangea Software has launched Nanosaur II: Hatchling for the iPhone and iPod touch. The game costs $3.99 and can be downloaded from the App Store immediately.

An iPhone port of Pangea’s popular Macintosh game, Nanosaur II puts you in control of a pterodactyl from the future who’s been sent n a mission to locate stolen dinosaur eggs and return them to the future by throwing them into wormholes. Yes, it’s a bit far-fecthed in concept, but hey, points for originality for sure.

You can collect special bonuses and weapons including heat-seeking missiles, cluster bombs and more, which you use to battle other dinosaurs that attack you and disable robotic sentries that fill the environment.
