In BHB, the player takes the role of the titular robot, a plucky little BioHazard Bot whose purpose is to carry out tasks too dangerous and unpleasant for humans. When an experiment goes bad, unleashing a plague of horrible creatures, it is up to BHB to clean up the mess and make the facility he works at safe for human use once again.
BHB is a 2.5d action sidescroller. The game features stunning 3d graphics, exploration, gravity bending physics, and combat that can take place in any orientation. The player proceeds through the game by exploring different regions of the facility and opening new ones by systematically wiping out any contaminations you may encounter.
