Cosmo Knight Zion – A New GBC Adventure in the Spirit of the 90s
Earth is under attack by androids from outer space. Zion and Eerie find themselves in the middle of the chaos – but instead of giving up, Zion grabs the cosmic armor of a defeated invader and launches a one-man crusade to save humanity. Sounds epic? It is.
Developed by Mexican studio ZeichiGames and published physically by Piko Interactive as the Standard Edition, Cosmo Knight Zion is a genuine love letter to the golden age of handheld gaming.
Gameplay & Features90s-Style Action Platformer
The game feels like a blend of Ninja Gaiden and Ghost & Goblins – with a hint of Saint Seiya on top. You battle through levels packed with enemies, collect power-ups, lose and regain your armor (giving it that Altered Beast vibe), and face off against powerful bosses.
- 5 stages with multiple levels and a boss each
- Secret bosses for hardcore explorers
- Hidden paths & secrets in every level
- Collectible gems that unlock bonus content
- In-game achievements
- Power-ups for combat variety
- Cosmic armor system – lose it when hit, win it back by fighting
Presentation & Atmosphere
The story is told through detailed pixel art cutscenes. The retro soundtrack pushes the GBC sound chip to its limits – fans describe it as an earworm. The visuals make the most of what the Game Boy Color can offer.
