The EMP Cannon is a 4x2 weapon room unlocked at level 10. The EMP Cannon fires a volley of three lasers in quick succession while consuming a maximum of five power. Each individual laser fired in the volley does 0.3 system damage, 0.5 shield damage, 0.2 direct hull damage, and an 8s EMP Stun. The cannon also needs to be refilled with Gas Gas, just like the Plasma Phaser.


In Combat

The primary purpose of the EMP Cannon is to stun lock rooms. The EMP stun effect will prevent the target room from being used and from having its power level adjusted. This cannon is best employed against the enemy’s cannons or victory condition rooms like the Hangar, Teleport, or even the Shield Generator. The system damage done by the cannon is negligible although the shield and direct hull damage it deals can help make the difference in a close battle.

When To Use

The EMP Cannon is considered to be mandatory at ship level 11 as it can stun lock critical rooms and provide a little extra damage on the enemy ship. However, due to the massive power and space requirements, fitting it in at level 10 can be challenging and is therefore optional.


There really isn't any magic AI for the EMP Cannon, just make sure it targets two important rooms so your EMP Cannon won't idle if the enemy doesn't have one of the rooms. Also, the EMP Cannon is categorized as a "Cannon" in AI coding.
