In the "Mine Is It Anyway?" level, stand inside the divot in the ground and shoot the Drill bot. When it extends its drills, it is about to charge. When this happens, duck inside the divot to avoid being crushed. Avoid the falling shards; you are not safe in the divot now. When you are falling, shoot the drills that are extended. Avoid the red laser and do not touch the sides of the walls. When the Drill bot fires its rockets, shoot them before they hit you. When the Drill bot attacks with spewing lava, stand to the far side of the wall to avoid it. Use grenades and continue shooting it until it is destroyed.
