Play Dinobasher Starring Bignose the Caveman (Europe) (Proto) Online

Dinobasher Starring Bignose the Caveman is a prototype for the Sega Master System, never officially released. It was developed by Sega, and it fits right in with the platform's library of early side-scrolling action games from that period.

You control Bignose, a caveman who must navigate prehistoric environments, jumping across platforms and avoiding enemies like dinosaurs and pterodactyls. The main objective is to progress through each stage, using rocks as your primary weapon to defeat foes. Signature mechanics include screen-by-screen exploration, projectile-based combat with limited ammo, and occasional boss encounters. The pacing is deliberate, and the difficulty can feel uneven due to its unfinished state. Playing it offers a glimpse into what might have been, with a mix of curiosity and slight frustration.
