The EMP Cannon is a 4x2 weapon room unlocked at level 10. It's the most reliable way of inflicting EMP to rooms because unlike the EMP Missile, the EMP Cannon's charges cannot be dodged with an Engine. Like the Plasma Discharger, the EMP Cannon requires Gas fueled ammo to fire.
The EMP Cannon is quite powerful and rather expensive power wise. Its high power consumption makes it rather hard to destroy, making 1-2 Armor blocks sufficient for protection. The EMP Cannon's charges can inflict nearly 10s worth of EMP, along with some other damage. This allows the EMP Cannon to stunlock rooms quite effectively. Additionally, make sure to refill its ammo after every fight.
When To Use
The EMP Cannon is the staple of level 10 ships, with little reason not to use it in most strategies. The EMP Cannon has the potential to lock down rooms like the Teleport, Shield Generator, and Hangar for the entire game if it's not disturbed. Its high space and power requirement may be hard to deal with, but its combat potential is immeasurable.
AI for rooms like the EMP Cannon can get rather complicated due to its importance and high power consumption. Due to the lack of available power in the later levels, having power efficient AI in a high power consuming room like the EMP Cannon is important. The below AI command requires all other rooms to have Increase Power By 1 to work. Basically, it soaks up any power lost when the enemy attacks a room but redistributes it every time a friendly room falls below 50% health. Since this will happen quite often, it'll help equally distribute power when it's needed.
Friendly Room HP < 50% -> Set Power To 1 None -> Increase Power By 1
