This single-seated spaceship was developed by the Rebel Army after the first invasion attempt by the Martians. It is specially designed to fight in space engagements against the Martians. It is stored at the very tip of the Rebel Missiles.
The Astro Slug is only equipped with a semi-automatic cannon on the top, but its true capabilities comes from its ability to equip special weapons during flight using two weapon pods on each of its sides along with its Vulcan units. It will lose a weapon pod if it sustains any damage, but it can be regenerated when another special weapon is collected or when the Astro Slug enters the Rugname. The Astro Slug also comes equipped with limited, powerful, unguided missiles that serve as firepower support.
Further on the mission while inside the Rugname, the Astro Slug can pick up a Vulcan power-up from an enemy which allows it to have two Vulcan units that move reverse of player movement (similar to the SV-001 Type-R in Mission 1). However, the Slug loses its Vulcan should it take any damage.
At the end of of the tunnel section, the Astro Slug crashes tip first into the ceiling, and the player exits from the rocket's top. If the Slug was destroyed beforehand, a Rebel Rocket appears in front of the player to assist in making a hole in the ceiling for them to enter.
In Other Games
The Astro Slug first appears as the icon representing the game's online mode. It would become a playable unit in the "Task Force 6th" Extra Ops.
The Astro Slug is rotated sideways with Marco using his jetpack goggles. It gains new weapons per special attack, and all of them fire at once. The stages are as follows:
- Semi-automatic cannon at a straight line.
- A Vulcan that aims in a spread.
- Weapon pods equipped with Enemy Chasers.
- Fires two unguided missiles.
At the fourth special attack, the Astro Slug ditches its weapons and attaches itself and an empty Astro Slug to a massive rocket. It then attacks by firing multiple unguided missiles. Its special is launching the empty Astro Slug and replacing it. Once the rocket is destroyed, the Astro Slug returns into its initial state and has to go through the process all over again.
By unlocking its 4th skill, the Astro Slug immediately deploys with the rocket.

|Astro Ship: A customized unmanned variant painted by yellow. Unlike the original, it uses its hammerhead to make damage, and it gets on top of the enemies to shoot the fire from its jet drift. Appears in Metal Slug Attack.|
- The Astro Slug, alongside the LV Armor, are the only Slugs to use special weapons as part of their armory.
