Type-07 Supergun

The North Korean Type-07 Supergun is easily the strongest variant of an artillery cannon in Mercenaries: Playground of Destruction.

Overview
Larger than any of the factions headquarters, the Supergun fires radioactive shells larger than an AN Abrams Tank. Capable of firing on targets all the way to Tokyo, Japan and Seoul, South Korea with its 50 foot long barrel, the Supergun is a power to be feared. The Supergun project was headed by Chin Chang and Ji An.

The real Supergun is only found on Kirin-Do Island, on top of a hill contaminated with radiation, under the watch of the Ace of Diamonds, and it is the main objective of the contract 'The Guns of Kirin-Do'. There are also two Prototype versions of the Supergun in the game. Both the Type-07 and its Prototypes are heavily armored, and require a powerful weapon, such as the Bunker Buster Bomb, the Cruise Missile Strike, or 2 rounds from another Type-07 to destroy them. The Type-07 proper also has a built in jammer to make calling air-strikes on it impossible, but is conveniently located within range of its prototype.

Tactics
The Type-07 Supergun is a very powerful weapon, but it is not very useful for the player. The viewfinder can't go below a predetermined height, making it impossible to hit targets on the ground at close distance. Additionally the weapon is slow to move and recharges very slowly. The only good use of the Supergun and its prototypes is to destroy the weapon itself during the related contract. The Supergun appears to be NBC shielded, meaning that the gunner is protected from the radiation in the area.

Real life
The Type-07 Super Gun is supposedly inspired by the Iraqi Project Babylon Supergun, which could launch WMD and conventional shells as far as Israel. Despite this, it has very little in common with the actual Project Babylon. In fact, it looks like and shares characteristics with conventional artillery cannons, but on a much more massive scale. It also resembles the German's "Schwerer Gustav" Dora Railgun which fired an 800mm Shell.

Trivia

 * Considering the fact that, while stationed on Kirin-Do island, it was mentioned to be able to hit targets as far as Japan, gives us an estimate that the supergun has a range in the thousands of kilometres. As central Japan and Kirin-Do have a distance of just shy of 1200km, it's pretty safe to assume it can likely hit targets even further with radioactive ammo.
 * Moving closely to the supergun it can be noticed that the gun is equipped with tracks that raise it from the ground, meaning that the weapon was supposed to be movable, unlike the prototypes that are fixed to the ground. Nevertheless in game it can't move anyway, similarly to the M1978 Artillery.
 * The Type-07 Supergun can be controlled by the player just like the prototype. The weapon is entered from the white door after killing the gunner on the cockpit with any explosive, preferably a tank so it can also offer protection against the radiation. This way it is possible to destroy the prototype before the actual supergun, consequently the contract will fail.
