What is Xenocider?

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:

• 60 Frames Per Second: On actual Dreamcast hardware, the game is buttery smooth.
• 4 Stages of Chaos: Each level ends with a multi-phase, screen-filling boss.
• Original Soundtrack: A thumping electronic/rock score by Abraham Rivas.
• Progressive Difficulty: The game is brutally hard, designed for 1CC (one-credit clear) runs.

Visuals & Presentation

• Graphics: Visually, the game sits in an interesting spot. It uses low-poly models that appeal to retro enthusiasts. The framerate generally holds up, which is a technical achievement for a 3D indie game on 20-year-old hardware. The draw distance is decent, and the enemy designs are distinct enough to identify threats quickly.
• Sound: This is the game's weakest link. While the sound effects are functional, they lack punch. The weapons sound flat, and the explosion effects are underwhelming. The soundtrack is a mix of synth-rock that fits the vibe but isn't particularly memorable.
