Battle Garegga

Battle Garegga is a vertically scrolling shoot'em up arcade game. The storyline takes place in a sort of dieselpunk version of the 1940s. Main heroes are brothers Brian and Jason — the sons of a genius designer who want to destroy the evil Federation. Players control planes (4 aircrafts to choose), fly forward, collect items and shoot enemies. Unlike in most other scrolling shooter games, where bullets are brightly colored to make them stand out from the background, bullets in this game are realistically colored, making them difficult to see. As a bonus, by entering a code, you can unlock four of the characters from Mahou Daisakusen.
