Bio-Hazard Battle is a 1992 side-scrolling shoot ’em up released for the Sega Mega Drive/Genesis and for the Sega Mega Play arcade platform. During G-Biowar I (the first global biowar) on the planet Avaron, a powerful new form of retrovirus was released as a deadly reprisal from the enemy. The viruses unleashed biological forces which couldn’t be stopped, leaving the planet filled with new and deadly forms of life. Gameplay: The game features a 2D side-scrolling shoot ’em up style of gameplay and the character chosen by the player can be moved in 8 directions by the D-Pad. The player can move, shoot, dodge, and block. To block an enemy projectile, the player must place the Power Star in the path of the projectile. There is also an array of different weapons at the ships’ disposal. Four different craft are available and each has different weapons. The player begins with a pre-set number of lives, from 1 to 5, 3 being the default. When a player is hit by a hostile creature or environment, their ship is destroyed and will reappear with one less life. Extra lives are attainable by absorbing 1-UP icons in the various stages, or reaching milestones for accumulating points without getting Game Over. 20,000, 50,000 and 100,000 points are the first three.
