This boss is one tough cookie, but here's a way to beat him without using cheat codes. First of all, get the boss to appear and start fighting you. Make sure you're close to a wall and no enemies are around, aim a little above the guy's head and fire a shaker missle. The missle will split into many missles as they hit the wall behind you and home in on the boss's glowing spot. You only need to do this one or two times and KA-BOOM! He's toast!
