icon Xenocider is a 3D arcade action game for the Sega Dreamcast created by Retro Sumus, the game has been developed for use with the custom built framework engine titled Dreamer and is an on-rails shooter with retro-futuristic aesthetics.


Xenocider is an innovative take on the on-rails shooter genre and the first 3D arcade game for the Dreamcast in over a decade. Inspired by classics like Space Harrier and Sin & Punishment, Xenocider will take players not only back to a time when arcade shooters where at the top of their game, but also to decades of adventure films and comic books which made us dream of a future of space colonization.
