Biohazard Battle is a simple, medium difficulty STG that excels in presentation. The game feels like it begins immediately. Its OST blares over the SEGA logo as soon as you turn it on, leading you seamlessly to its start menu. After selecting your ship, the game begins as its dropped from a large mothership and the player ship descends from space through the planet's atmosphere and then finally the horizontal shooting segment that takes up the rest of the game. The slow blending of the black space and the blue atmosphere effect, the crescendoing music, the transition from the logos to the menu to the game itself, all as the OST supports these images—it achieves a unique cinematic effect that I not only haven't seen in other shooting games, but in many games period, even those whose whole purpose is to blend cinema and gameplay.

The remaining game has a sense of cohesion and verisimilitude as you travel through various biomes and take down the bug themed enemies. Its a pretty good console horizontal shooter, with caveats. The power up system is somewhat limited—there are a few different colored pick-ups as usual, but there's no upgrade system you usually see in STGs, so it makes the gameplay feel samey even though the levels and enemies have unique and interesting designs. It's always fun though. What really sets it apart is its presentation and style, not its gameplay.
