Overview and Gameplay
A biological war has transformed the planet Avaron into a hostile world of mutants and living machinery. In Bio-Hazard Battle, one or two players pilot organic Bioships through eight horizontally scrolling stages, searching for a place where humanity can return.
Each of the four Bioships has a fixed speed and its own combination of weapons. A floating Power Star follows the ship and changes its attack when colored Energy Seeds are collected. Repeated seeds raise the current weapon through three power levels, while losing a life reduces its strength. The campaign moves through ruined cities, forests, mines, ocean depths, a flying destroyer, and the Biowar laboratory.
Controls And Mechanics
- Directions: Move the Bioship in eight directions and reposition the Power Star.
- A: Use rapid autofire.
- B or C: Fire manually, or hold and release to launch the powerful Plasma Wall.
- Start: Begin, pause, or resume play.
Two players can fight simultaneously in cooperative play. Both choose their own Bioships, although one ship can sometimes obstruct the other player’s Power Star fire.
Version Notes
The western release is titled Bio-Hazard Battle. In Japan it was released as Crying: Aseimei Sensou. The shared USA and Europe version adds rapid fire to Button A.
