Bio‑Hazard Battle is a visually striking, side‑scrolling shoot‑’em‑up for the Sega Genesis that drops players into a hostile alien world overrun by mutated organisms and biomechanical horrors. Piloting one of four advanced bio‑ships, players must blast through swarms of grotesque enemies, navigate organic landscapes, and survive intense boss encounters as they fight to reclaim the planet Avaron from a deadly parasitic outbreak.
