Wild Guns/WMG

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

• Desolation Canyon- Fire (tank attacks with a flamethrower and incendiary missiles)
• Gold Mine- Water (it's a Giant Enemy Crab)
• Armoured Train- Air (the jetpack dude flies)
• Ammunition Depot- Earth (it's based off a snake or worm, something which lives in the ground/under a rock)
