Story Behind The Song

It's in the distant future the year 3000 and two factions (The merchants and the aboriginals) are fighting for power. the merchants are small in number but have robots and the aboriginals are like a tribe of orcs.The scene starts with a spear being thrown at a lone robot. Then the robot opens fire but is quickly subdued by a hoard of aboriginals. Things escalate as more robots join the fight and rip through the hoard with automatic gunfire and thermite bombs. The hoard scatters except one crazy warrior standing alone with a crossbow.
