Class-2 directed energy cannon

Twin Plasma Cannons are standard weapons mounted on light vehicles, like the Ghost or the Banshee.

Summary
The Twin Plasma Cannons are directed energy weapons capable of firing automatic bursts of superheated plasma (in the 100-250 kW range). It is a very powerful against energy shields, but not so powerful against flesh.

Its major advantage is its rapid rate of fire: 420 to 600 projectiles per minute, making this powerful against light vehicles and infantry, but not so good against tanks.

It uses energy from the power core of the vehicle where it is mounted, and, when it uses the boost, it cannot fire.

Trivia

 * When you are hit by a plasma bolt fired from this weapon, you run slower.
 * While boosting, you cannot fire the Plasma Cannons
 * In Halo: Combat Evolved, the Twin Plasma Cannons fired simultaneously, while in Halo 2 and Halo 3, they fire one after the other.
