The Bull Drill is an advanced construction site machine/digger, used by the Rebel Army. It is the first boss found in Metal Slug 6.


The Bull Drill is a large excavator used by the Rebels and is primarily designed to dig underground with ease. It has both a bulldozer blade and drill, hence its name.


You meet this boss in mission one. It attacks by sending a demolition drone toward you from underneath its giant shovel at the front. A rebel soldier then pops out and attacks with the energy cannon. It sometimes moves forward to ram you or fires the boulder. Once you get rid of half its health, the shovel will blow up, along with the rebel and bomb attack, at which point it will begin using its drill. It can extend the drill similar to the Drill Slug and try to hit you, or lift it up to the ceiling and drill it, causing boulders to fall on you. In easy mode, however, it doesn't use its drill.


  • The Bull Drill official name was revealed in Metal Slug Defense 1.27.0 Update.
    • In MSD. The Rebel on its Giant Shovel has been removed, and the shovel cannot be destroyed except when the HP of The Bull Drill reaches 0 and gets destroyed.
    • The Bull Drill's special attack in MSD is to drill the edge of the screen and cause a boulder to fall. This attack can destroy all kinds of aircraft below its drill (except Sol Dae Rokker and Hairbuster Riberts which have very high HP), making the Bull Drill one of the best choices to use as an anti-air unit.
