Xenocider

Xenocider is a fully 3D arcade rail shooter for the SEGA Dreamcast, openly inspired by the classic Space Harrier. As the cybernetic fighter Xara you race toward the screen, dodge barrages of fire, destroy waves of enemies, and face giant bosses on exotic planets. A custom 3D engine, brisk pace, and vivid visuals show that the Dreamcast still has plenty to offer years later. Released on a real GD-ROM disc in a boxed edition, it ranks among the most technically ambitious works of today's Dreamcast homebrew scene.
