The Rugname returns as a miniboss and serves as the location for mostВ of the game's final mission. The Dai-Manji detaches and explodes, releasing Morden who is chained up to a metal slab. The Landseek will leave after a few seconds, taking the parked SV-001 and still tied Hyakutaro with it.ДЄfter a long fight, a Rebel piloting a Eaca-B will make a kamikaze attack into the Rugname's core, making it retreat into space. In Metal Slug X, Hyakutaro is also brought in. Halfway through the fight, an invincible Landseek backs up with an SV-001 on its back. Grenade Soldiers, Shielded Soldiers, and Girida-Os assist the player as extra damage and as shields from the Mini-UFOs lasers. Because the cannon will always hit the same spot, the larger threat is the unlimited horde of Mini-UFOs. The Rugname's massive size makes it an easy target all the player has to do is aim upwards. Luckily, the cannon can only be aimed straight down, so it relies on its infinite supply of elite, extra-durable Mini-UFOs for additional defense. The Dai-Manji's deadly electric beam is replaced with a devastating laser cannon.

The Rugname's only weapons on the underside are channeled through the attached Dai-Manji. Forcefully severing Rootmars from the ship results in total system failures, causing the ship to collapse into the atmosphere. However, the only way to destroy the Rugname for good is by attacking the Martian leader Rootmars, who controls every aspect of the ship with its brain. The Rugname can be temporarily defeated by destroying its attached Dai-Manji. However, its description in Metal Slug Attack says that its size is that of an entire city. The official explanation for this is that the hallways of the Rugname are arranged in a giant spiral, allowing for a large continuous corridor from the rim to the center. However, during the second 'vertical space shooter' segment in Metal Slug 3, the player spends several minutes flying through the Rugname. It is very heavily armored, and far too large to destroy with regular weaponry.ДЄccording to its concept art, the Rugname is only 140 meters in length and 23 meters in height. The Rugname serves as the Mars People's mothership from which troops are dispatched.
