This is a relatively simple boss to defeat.
There are three main points when fighting this boss.
A) Run away when he pursue's you or he will crush you and you die.
B) Bikes drop their oil in front of the boss when he is pursuing someone to help them get away, it slows the boss down.
C) Stack up the pyreite together and lead the boss towards it, when he is there, blow up the pyreite to do huge damage to the boss.
Lets get passed the boss all the time and concentrate on more serious bosses.
