Aargh! Bozon is coming. He's bad, he's mean, he's mad - and he's planning to take over the world. Help! Eek! Oh no!
Luckily, the Earth has two iron-pumping heroes who are so hard they'd jet-pack to the centre of Bozon's domain and destroy it any day of the week.
Firing at the energy pods the enemy leaves behind turns them into different types of weapon (mega-bazooka launcher, tail-gun, 3-way shot, etc).
Oh yeah - a few bonus icons (extra points, shield, improved firepower) are dotted around the environment as well. Cool, huh?
