Metal Slug Wiki

The Drill Slug is a special Super Vehicle featured in Metal Slug 3 and a purchasable unit in Metal Slug Defense.


The SVX-22UG Drill Slug is a drilling machine designed to dig tunnels. The drill is equipped with Vulcans for long ranged engagements and a drill on the chassis for close-range combat which will automatically activate whenever something touches it. Also, instead of a cannon, the Drill Slug extends its 400mm bore drill from its chassis instead, which is especially useful against the Giant Caterpillars; which may take 1-3 extended drill attacks to kill one.

While it is fairly slow and unable to jump, it is compensated with its ability to lift the cockpit; giving it a higher profile and to avoid incoming fire from below. Although the player will need to be careful as it is still vulnerable to some attacks.

The player can only use the Drill Slug in the lower paths Mission 4 in MS3, which requires the player to open a hatch in the wine storage area in the bottom path.

Special Drill Slug: A red variant of the Drill Slug, operated by Tarma Roving. The drill is expendable and can be launched at enemies, slowing upon impact for massive damage. Appears in Metal Slug Attack.
Regular Drill Slug: A blue variant of the Drill Slug, operated by Regular Army personnel. It's a weaker version of the Special Drill Slug, in which its drills deal less damage, but it shoots an additional drill and each one explodes at the end. Appears in Metal Slug Attack.
Golden Drill Slug: A golden variant of the Drill Slug. It is much more durable than its predecessors, and is piloted by Fio Germi. She can throw bait to attract a Poison Snail, which she promptly kills and uses its shell as a shield of sorts to take incoming damage and poison enemies with it. Appears in Metal Slug Attack.
Mega Drill Slug MSA idle.gif Mega Drill Slug: The largest version of the Drill Slug, operated by Marco Rossi and Fio Germi. This biggest variant is developed for use against large targets. Its massive drill has enough destructive power to rip through anything. Appears in Metal Slug Attack.


  • The Drill Slug has a bug that if the player stays in the Slug as it explodes, the mid-air acid death animation is used instead of the mid-air burning death animation.
  • It has a special animation for killing Big Snails, which would also drop random items
  • It's extendable drill is very useful against a line of weaker enemies in one succession.
