Asteroid Defense System Cannon

The Asteroid Defense System, or ADS, is a large fixed Array of Mass Drivers used on board many Planet Cracker-class ships. Its primary goal is to track and destroy asteroids automatically, preventing damaging collisions with the ship. However, in the event that a part of the ADS goes offline, a crew member will have to manually control an offline ADS Cannon.
Overview
An ADS Cannon is made of a Mass Driver controlling two barrels that can fire separately. One can override the Cannon manually and fire it on its own. When firing one of the barrels it can fire a long lasting fast rate of fire, eventually the Barrel will overheat and needs to cool down for a few seconds before being operational again. When firing both of the barrels it can fire a short lasting, even faster, rate of fire. When firing both the barrels will overheat much faster, but the impact from the mass driver is far greater.
The ADS system implements automated firing systems to automatically target and destroy incoming asteroids and debris.
Hull Integrity indicates the current percentage of Hull intact enough to support the most important systems located directly under the hull. When decreasing, smoke and fire will start to ignite around the ADS Cannons, if it reaches zero, one will be blown out of the ADS Cannon seat and die of debris and the airless space that will exist at that point.
There are two instances in the game that require the player to control an ADS Cannon. The first is ADS Cannon 47 when Zero Medina & C2 Medina has reignited the Engine and Gravity Centrifuge, the ship tries to regain orbit, but would pass through the debris from the planetcrack.
Combat Tips
*When firing at larger asteroids it is advisable to use both of the barrels to destroy the asteroids, smaller ones can be easily destroyed with one barrel.
*Do not fire if there is nothing to fire at!
*A lot of debris that can be shot doesn't inflict damage to the hull, only the asteroids flying closer to your location seem to hit the Ishimura.
*Try to take small breaks between firing, this will decrease the chance of a barrel overheating.
*When fighting The Rivera Federation Airborne Attack, they try and hit all five of its Missiles and Payloads every two seconds. If done correctly, it won't have time to hurl any explosives or debris at the Ishimura because the tentacles are too busy taking damage.
**UCAVS and B17's' won't last long against a dual barreled concentrated rate of fire.
Trivia
* Presumably, the Mass Driver technology mentioned by Young Harrison Rivera when using the ADS functions similarly to today's Mass Drivers. Today's Mass Drivers use a type of electromagnetic catapult that uses a linear motor to propel payloads at high speeds. This is also classified.
*"Miniaturized" mass drivers can also be used as weapons in a similar manner as classic firearms or cannons, using chemical combustion.
