In-Game Description
"This Super Crossbow Rotary Ground Drill was brought into Arabian underground ruins by Morden's Army"
Assy Nero MSA idle

The Assy Nero is a Super Rare unit in Metal Slug Attack, first appearing in the Extra Ops titled "Golden Soldier". Currently, Assy Nero's parts can be obtained through the Regular Army's second chapter in Another Story dubbed "The Sand Kingdom and the Golden Hero".

When deployed, it initially hides underground - although players can still see where it is via their radars. When it reaches an enemy ground unit, Assy Nero will burst up, and will also destroy projectiles that are above it when it appears. Enemy units that touch Assy Nero will also be damaged when it appears. The damage it deals when appearing increases greatly when MSA Skill small + 4 is unlocked.

Once it appears, Assy Nero will stay there (like units built by the Miner), launching missiles at the enemy as a standard attack. It's high health and large size give it good tanking capabilities, though it fares poorly against units like Cleopatra who can destroy it with ease. Sending Assy Nero with a large amount of similarly sized units (like the Big Shiee) can surprise opponents.

Compared to its MK II variant, it's inferior in almost every way - it costs more, and has far less health and damage. Its inability to move can also make it problematic if it appears in the wrong spot, though it can serve as a nice back-up wall if that occurs.

When Assy Nero, Big Shiee, and The Keesi II are placed in the same deck, they form the "Second Rebellion" team, lowering their AP costs by 15%.

Attacks

Long Range

Attribute grenade Drilling Missile (Spread) - Fires seven homing missiles from its mouth.

Special Attack

Attribute grenade Electromagnetic Convergence Ammo (Spread) - Seemingly goes idle before a big blast of energy erupts from its mouth. A large boulder shortly appears and crushes enemies in front of Assy Nero.
