Play Bio-Hazard Battle (World edition) Online

Choose Practice or Easy and raise the life stock in Options while learning, then select one of the four bioships; their speed and weapon behaviour differ, so try each before committing to a harder run. Keep moving and let the orbiting Power Star absorb or intercept danger while you fire. Collect yellow, orange, blue, and green Energy Seeds to change the Star’s weapon, and learn which colour suits the current enemy pattern. A provides convenient autofire, but switch to B or C when you need the Plasma Wall attack.

D-pad: move the bioship and navigate menus. Start: begin or pause. A, B, or C: fire; A supplies autofire but cannot activate the Plasma Wall, so use B or C for that weapon. Fly over coloured Energy Seeds to change the Power Star weapon. The Power Star travels with the ship, acts as both a weapon and a protective satellite, and changes its attack according to the seed colour collected.
