The Iron Sentinel, also known as Armored Missile Tank[1], is the second boss from Metal Slug 6.

Information

The Iron Sentinel is a giant mobile rocket launcher/tank operated by General Morden. It is heavily armored, meaning the weak spot is the giant cannon on top. It is also armed with various missile launchers and energy cannons.

According to Metal Slug Attack, this huge tank was made in cooperation with the Mars People, which explains why the tank has energy cannons and requires Mars Energy in order to upgrade its skills.

Boss Synopsis

The Iron Sentinel's weak spot is the large cannon. Its first attack is to shoot three rockets from its giant cannon at the top. The rockets will then crash onto the ground. The second attack is to fire arching projectiles from the turrets at the side. Another attack is to launch small missiles from the side of the tank, and the missiles will fly in multiple directions which are relatively easy to avoid or destroy.

Once the cannon is destroyed, it will reveal a huge rocket launcher. When launching the rocket, sparks fly out, but they can be dispatched with gunfire. The giant rocket flies off-screen and then crash to the ground, causing a massive explosion. The explosion sometimes give out items like an HMG crate. When the Iron Sentinel is aflame, the process of launching the giant rocket speeds up, but the rocket is still easy to avoid. Once it suffers enough damage, the tank will crash into a hill.

On Easy mode, the Iron Sentinel does not shoot rockets from its cannon.

Variants

In Other Games

Metal Slug Attack

The Armored Missile Tank appears in the 1.8.0 update where it was renamed to the Iron Sentinel. Its unit parts can be purchased via Mars Shop at a cost of 1000 Mars Coins per part. Skill items are also bought with Mars Coins. The player can earn Mars Coins by trading excessive parts of Units that have reached the Platinum frame. The Iron Sentinel is one of the few units that gets buffed over time to justify the long-term commitment necessary to unlock all four skills.

As the Iron Sentinel's sprites are at an angle, this game rotates it in real time.

Trivia

  • The Iron Sentinel, its cannon, and main cannon ammunition is based on the German WWII Super Heavy SPG Landkreuzer P1500 Monster, the Germans siege cannon Karl-Gerat, and the German Fieseler Fi-103 (aka V1 Rocket), respectively.
  • The Iron Sentinel was used to be known by fans as the Iron Slider before its official English name reveal in Metal Slug Attack.
