Giga Wing is a vertical Shoot'Em Up series developed by Takumi and published by Capcom for arcades. It is perhaps best well-known for two features: * The Reflect Barrier shield, which takes whatever masses of bullets touch it and reflect them back, often inflicting massive damage upon enemies. * The scoring system. Due to some scoring mechanics in which collecting one of many, many medals increases the value of the next one, and your medal count acting as a score multiplier, it is easily possible to have a score well beyond the scale of most other games' scoring systems.
