Nanosaur

Nanosaur is a free, open-source 3D action game originally released by Pangea Software for Macintosh computers in 1998. Players control a cybernetic dinosaur sent from the future to prehistoric Earth shortly before an asteroid impact. The mission involves exploring dinosaur-populated environments while completing objectives under a strict time limit. Players must navigate dangerous terrain and survive encounters with hostile prehistoric creatures. The game combines exploration, shooting mechanics, and fast-paced movement in a fully three-dimensional world. This modern source port preserves the original gameplay while introducing support for contemporary resolutions and correcting legacy bugs. Available for Windows, macOS, and Linux, it recreates the classic Macintosh experience on modern systems.
