i nailed his feet and right arm. then cut off his other fore arm. then beat him with it. i beat him so hard that the forearm exploded so i used a leg...his bottom half came off and he is still alive.
i found this really helpful glitch...once you get the sawn-off shotgun equip it to your main and the chainsaw as your backup, now switch between the weapons (this works best when the chainsaw has full ammo) and shoot, if done right you will have 99 ammo for the sawn-off shot gun,
2/5 for most of the game...but the fact that the arms don't do the most smart thing and you have to program them makes it a lot more fun...adding another 2/5 the music i would add a 3/5 but i can only add a 1/5
total=5/5
