WMG / Wild Guns

The bosses of the four selectable levels are based off the four classic Greek elements (Earth, Fire, Wind, Water)

  • Desolation Canyon- Fire (Grand Dragon — a tank that attacks with a flamethrower and incendiary missiles)
  • Gold Mine- Water (Giant Crab — a Giant Enemy Crab, and is thus modeled after a water-based creature)
  • Armoured Train- Air (Flash Boy — a guy on a jetpack, who obviously flies)
  • Ammunition Depot- Earth (Geas Crystal — a snakelike robot which essentially has a giant gemstone over its core)
