If you are reading this blog, you already know the mantra: The Dreamcast never dies.
While Sega officially pulled the plug in 2001, the scene has been kept alive by a dedicated community of developers and publishers. For years, we’ve been blessed with 2D shooters, puzzle games, and shmups. But high-octane, third-person 3D action? That is a rare breed in the world of indie Dreamcast releases.
Enter Xenocider, the latest title to land on physical media for the legendary white box. Developed by Retro Sumus and published by the team at Wave Game Studios (and available in the popular CD-i style case format), this game promises to fill that Space Harrier-sized hole in your heart.
But does it stick the landing, or should it have stayed in the atmosphere? Let’s dive into the Dreamcast CD-i release of Xenocider.
Alternative: DiscJuggler (original CDI creator) or CDI Burner Tool (simpler).
Let’s get technical for a minute. The Dreamcast’s GD-ROM held 1GB of data. A standard CD-R holds 700MB. To get a game running on burned media, you usually have to downsample audio or strip FMV.
Xenocider doesn’t feel like it was gutted.
The CDI (DiscJuggler image) floating around is a masterclass in data density. The developers managed to pack high-color textures, a thumping electronic soundtrack, and smooth LOD (Level of Detail) transitions onto a disc that costs $0.30 to manufacture.
Developed by Retro Sumus (a Spanish indie team known for Ziggy the Chaser and Alice’s Mom’s Rescue), Xenocider was originally funded through Kickstarter and released physically in 2019. Unlike many modern retro titles that get ported to Switch or PC, Xenocider was built specifically for the Dreamcast’s proprietary Windows CE architecture.
The Premise: You pilot an alien bio-weapon—a living starfighter—through hordes of mutated creatures. The game is a pure 3D rail shooter. You don’t control movement; you control a reticle, blasting everything on screen while dodging incoming fire with shoulder-button barrel rolls.
Key Features:
Let’s talk about the audio. A lot of homebrew Dreamcast games sound like MIDI files composed in a bedroom. Xenocider sounds angry. The soundtrack is heavy, industrial techno mixed with orchestral stabs. It sounds like Unreal Tournament meets Terminator.
The enemy design is grotesque in the best way. The CDI contains sprite work that rivals Ikaruga. The alien queens have translucent wings. The mechs have heat haze coming off their exhaust pipes. It is absurd that this is running on the same architecture as Sonic Adventure 1.
Xenocider is a commercial homebrew – you must purchase it legally. Burning your own backup is permitted if you own the original disc. Do not download CDIs from unofficial sources.
If you need help finding the correct CDI version (e.g., 1.0 or 1.1), check the official RetroSumus store page or the developer’s Twitter/X account for updates.
