Pile Driver is Impact Man's Special Weapon in Mega Man 11. Once Mega Man obtains it he gains a special air dash ability that allows him to attack opponents he rams into which shoves them off into an explosion.
Using this weapon with the Power Gear, enhances this attack, giving Mega Man a longer dash and a greater explosion.
Just like the other Special Weapons in Mega Man 11, Pile Driver alters Mega Man's physical appearance when equipped, rather than simply swapping his colors giving him Impact Man's helmet (without the spike) and jackhammer arm for his left arm so Mega Man can perform the attack.
- This weapon's air dash attack capabilities is similar to the Speed Burner's charge attack from Mega Man X2 and Mega Man Xtreme.
