of the game is to collect the eggs of five dinosaur and flying reptile species and deposit them in time portals to the future in twenty minutes; at the end of the countdown, the asteroid that caused the Cretaceous–Paleogene extinction event hits Earth. The Nanosaur is equipped with a "fusion blaster" (a basic multi-purpose energy weapon), a jet pack allowing flight, a temporal compass for locating time portals, and a GPS locator for navigation. The native animals will attack the Nanosaur when their eggs are threatened; species encountered include Tyrannosaurus rex, Stegosaurus, Triceratops, Dilophosaurus (who spits venom as in Jurassic Park), and the flying reptile Pteranodon. As well as hostile creatures, the Nanosaur must also avoid water and lava, environmental hazards which slow the player down (or kill it). Legacy The game was being ported to Linux by Three Axis Interactive, but the port was never completed. Around 2003 the source code of the game was made available by the developer under a restrictive license. In 2021 an open source version of the game utilizing OpenGL was ported to modern systems (Windows, Mac, and Linux) with the developer's blessing by Iliyas Jorio. Jorio had previously ported their other title, Bugdom, to modern systems in 2020. Nanosaur Extreme is another version of Nanosaur, released at a later time with heftier system requirements. It has many more enemies and weapons than Nanosaur, and it is described on the Nanosaur downloads page as "what Nanosaur was meant to be – a total kill-fest". Nanosaur 2: Hatchling, a continuation of the original Nanosaur storyline, was released in March 2004. Nanosaur 2 is the first stereoscopic game released for the Mac.
